Hipster Harmony: The Hybrid Syntax of Seventh Chords in Post-Millennial Rock

Abstract

This article argues that art-rock groups active since 2000 often use chromatic progressions between seventh chords and other chords of four or more notes in order to differentiate themselves from generic rock styles. These groups introduce chromatic progressions through one of three schemas: altering a recurring diatonic progression (a recurring Roman-numeral progression), exploring the voice-leading possibilities of a recurring chord (a magic chord), and exploring the diatonic and chromatic possibilities of a voice-leading motion (a magic voice leading). When a chromatic progression appears, it functions as a large-scale, tonally undetermined alternation between two chords, or as a substitution for a normative progression. Hybrid syntax occurs where progressions arising from the techniques listed above are juxtaposed with common rock progressions. I analyze instances of hybrid syntax in songs by Dirty Projectors, Deerhunter, Mew, Grizzly Bear, and Radiohead. In these songs, chromatic progressions conspire with lyrics, timbre, and texture to convey otherworldliness or ambiguity, supporting the depictions of unusual personae or situations that art-rock groups favor.

[0.1] Many rock critics recognize that a broad genre of rock music has emerged since around 2000. Often labeled "art rock" or a similar term such as "experimental pop,"⁽¹⁾ this genre is characterized by unusual timbres often incorporating high vocals, combination of sounds from a broad array of styles, and projection of a progressive ethos through means other than overt displays of virtuosity (Osborn 2010, 54-56). Representative bands include Animal Collective, Dirty Projectors, Mew, Radiohead, and St. Vincent. Other bands, such as Deerhunter, Grizzly Bear, and Tame Impala, are sometimes assigned related labels such as "chamber pop" or "neo-psychedelic" their music nonetheless displays similar characteristics. ⁽²⁾ Music critics writing about art-rock bands often note the complexity or intricacy of their textures, using descriptors that range from "lush and opulent" to "difficult and cerebral."⁽³⁾ This textural intricacy places the genre in the legacy of 1990s indie rock, which, as David Blake points out, uses timbral heterogeneity as a primary means of expressing differentiation from the musical mainstream (2012, [8.4]).⁽⁴⁾ In addition, while art-rock artists sometimes engage in formal experimentation, unlike neo-progressive bands, they tend to write concise songs. Critical circles that favor art rock, such as the well-known music criticism website Pitchfork.com, praise the artists' autonomy from the mainstream, presentation of a unique or ambiguous lyrical persona, and meticulous craft. The positive appraisal of these characteristics is evident from Pitchfork's numerical ratings: with a few exceptions, the site gave each of the albums containing the songs discussed in this article a rating of 9.0/10 or higher. ⁽⁵⁾

[0.2] This article explores another facet of post-millennial art rock that has received little analytical attention: chromatic experimentation. Not all art-rock bands explore unusual chromatic harmonies, and some do so only infrequently, but there are enough striking examples to consider chromaticism a feature of the genre. Chromaticism helps art-rock bands assert a progressive ethos that distinguishes them from contemporaneous generic rock styles, and it links them to earlier styles that engaged in similar experimentation. This article thus complements studies of chromaticism in other rock styles by Capuzzo (2004), Everett (1997, 2008, 2012), Harrison (1997), Holm-Hudson (2008, 2010), Kochavi (2002), Reale (2014), and others.

[0.3] Previous studies of chromaticism in rock music largely use the interpretive lens of tonal function,⁽⁶⁾ or they adapt labels from neo-Riemannian theory, focusing on parsimonious voice leading among triads.⁽⁷⁾ By contrast, many art-rock bands use chromatic progressions involving thicker chords that contain four or more notes. Their music is thus a proving ground for exploring chromatic voice-leading relations among seventh chords, and it allows for an expansion of previous studies of rock chromaticism. This article defines common types of chromatic progressions occurring in recent art rock, and it identifies harmonic schemas that many post-millennial art-rock songs use to introduce and incorporate chromaticism. The schemas are classified both by the functions of chromatic chords, and the ways in which chromatic progressions are introduced. Chromaticism in art rock, as in classical music, has strong potential for evoking unusual states or creating expressive intensity. Accordingly, the analytical examples in this article also demonstrate that chromaticism conspires with lyrics, vocal performance, timbre, and instrumental texture in order to suggest otherworldliness, ambiguity, or disjuncture.

1. Two Examples of Chromatic Progressions

[1.1] "Offspring Are Blank" is the first track from Dirty Projectors' 2012 album Swing Lo Magellan. The chorus of the song has musical features that one would expect of an opening track aiming to grab listeners' attention: loud drums, shouted vocals, and grungy, low distorted guitars. But the introduction and verse play against the chorus's type; they create an eerie atmosphere through references to exotic folk styles, a melodic line that uses wide leaps and intricate rhythms, a sparse texture, and cryptic, paradoxical lyrics. In keeping with indie styles' use of timbre to show differentiation from the mainstream, the texture is deliberately sparse instead of full (Blake 2012, [8.4]). In addition, the chromaticism in the opening sections reinforces the sense of otherworldliness and eeriness.

[1.2] The song's introduction, shown in Figure 1a, uses a melodic line drawn from a BPhrygian scale that alternates between lowered and raised , which is often a marker of exoticism or folk music in rock (Tagg 2009, 121-23).⁽⁸⁾ Other musical features reference the folk genre of a prison work song, evoking temporal as well as geographic distance. The section suggests group singing by presenting the melody in multiple voices and multiple octaves (achieved by lead singer David Longstreth quadruple-tracking his voice). Heavy handclaps that are not perfectly synchronized resemble the sound of axe-falls or hoes striking the ground. ⁽⁹⁾ There is no accompaniment other than the handclaps. Prison work songs do not, in general, use Phrygian scales; instead, the two stylistic references combine to indicate a synthetic "otherness" that contrasts sharply with normative rock styles.⁽¹⁰⁾ The disparate stylistic references are made eerie through an unusual soundbox (Moore 2012, 29-38): the singers are preternaturally close to the listener, filling the space on both sides of the stereo field but without the reverb that would suggest depth.

Figure 1b. Dirty Projectors, "Offspring Are Blank," verse 1 (drums not shown)

[1.3] Locke observes that musical exoticism allows a composer to "distort the stylistic norms of his or her musical tradition (until they sound 'different') or. . .even invent a startling style feature outright" (2007, 482). A musical distortion of this nature occurs in the verse, which opens with chromatic progressions that substitute for those drawn from the melody's Phrygian scale. These progressions reinforce the unnatural eeriness provided by the stylistic markers and production techniques. The first verse, shown in Figure 1b, adds backing vocals along with a sparse electronic drumbeat. A harmonic reduction is shown underneath the score; this reduction assumes enharmonic and octave equivalence and arranges the chords so that each finds the shortest possible path to the next. ⁽¹¹⁾ Each chord is identified above the staff, with analytical labels below: the suffix "7" indicates a major-minor (i.e., dominant) 7th, "o7" indicates a fully diminished 7th, "ø7" indicates a half-diminished 7th, "9" indicates an added ninth, and "m" indicates a minor triad. The labels do not take chord inversions into account.

[1.4] The first six measures of the verse divide into opening and closing phrases (Moore 2012, 85). Measures 1-2 comprise the opening phrase: in each measure the harmonies move from a tonic to a non-tonic chord. Measures 3-6 comprise the closing phrase: m. 3 moves from a non-tonic to a tonic chord, and mm. 4-6 do the same but double the duration of the harmonies. These measures (4-6) contain the recurring diatonic progression II ⁹-i. In the harmonic reduction II⁹ is relabeled "Phr.N" for "Phrygian neighbor," a chord that leads to the tonic and contains Phrygian's characteristic . In m. 3, vii^add6 acts as a substitute Phr.N., and the tonic is altered to become a major-minor 7th chord, using raised from the melody.⁽¹²⁾

[1.5] The opening phrase substitutes two different chords that contain for the Phr.N: m. 1 uses Co7 and m. 2 uses G7. In the reduction, the substitute chords are preceded with an "approximately equals" sign (≈) below the staff. Solid lines connect voices that move by semitone. Until the diatonic progressions at m. 4, no progression involves more than two units of voice-leading work-that is, the total number of semitones that all the voices move in the idealized voice-leading space shown in the reduction is two or fewer (Cohn 2012, 6), creating a smooth harmonic motion. ⁽¹³⁾ The first three measures wring a great amount of harmonic variety from these limited voice-leading motions, as they demonstrate three different types of progressions: parsimonious, contrary-motion, and similar-motion. In a parsimonious progression, a single voice moves by semitone (Cohn 1996), as in mm. 1-2, where Bmoves up by semitone to lead from B7 to Co7, and then moves back down to the original chord. In a contrary-motion progression, two voices move by semitone in contrary motion to connect two seventh chords of the same type, as in the B7-G7 progression in m. 2. Finally, in a similar-motion progression, two voices move by semitone in parallel motion to connect two seventh chords of different types. ⁽¹⁴⁾ Two similar-motion progressions occur in mm. 2-3: G7-Fø7 and Fø7-B7. The chords are part of a Boretz region-that is, they are minimally displaced from a central diminished-7th chord (Cohn 2012, 153-55; Boretz 1972, 185-90).⁽¹⁵⁾ In addition to the arched trajectory of its open and closed phrases, the first verse effects a gradual transition from the least normative to the most normative progressions. It begins with a Boretz-region progression that is a chromatic transformation of the modally altered Phrygian progression (mm. 1-2), proceeds to the modally altered Phrygian progression (m. 3), and ends with a completely diatonic Phrygian progression (mm. 4-6). This motion from exotic to normal reflects, on a small scale, the stylistic shift that occurs from verse to chorus. ⁽¹⁶⁾

[1.6] In "Offspring Are Blank," several smooth chromatic progressions provide colorful substitutes for a Phrygian progression. By contrast, the opening of My Bloody Valentine's "Is This and Yes" (2013), shown in Figure 1c, uses only a single chromatic progression. The track contains long chords played with an organ-like synthesizer sounding over repeated pedal notes played on timpani. The chords are almost entirely from the "white-key" diatonic collection, and vaguely suggest C as tonic. The first two chords use the contrary-motion voice leading B-Band F-E to link two minor seventh chords in the lowest four voices, shown with solid black lines in Figure 1c. The contrary motion occurs not only in abstract pitch-class space but literally in pitch space in the lower register. The progression creates a change of diatonic collection over a stationary bass and melodic note, paradoxically suggesting stasis and motion simultaneously and contributing to the song's dreamy, confused atmosphere.

2. Mapping Chromatic Progressions Involving Seventh Chords

Figure 2a. Tube-shaped voice-leading map for seventh chords

[2.1] Because the parsimonious, contrary-motion, and similar-motion progressions are used frequently in art rock, it is valuable to identify all of their possible iterations in order to determine the range of options a song is selecting from. Figure 2a performs this task for parsimonious progressions by mapping four types of seventh chord onto a three-dimensional tube. ⁽¹⁷⁾ Each circular cross section, outlined with a dotted line, contains chords of the same type, and two chords connected by a line segment are parsimoniously related.⁽¹⁸⁾ At the leftmost end of the map is Co7. Four segments emanate from this chord to show that each of its members can be lowered by semitone to form a major-minor 7th (i.e., a dominant 7th). Each major-minor 7th can lower either its 3rd or 7th to form a minor 7th; hence, two lines emanate from each major-minor 7th to connect with the minor 7ths in the third cross section. Similarly, each minor 7th connects to two half-diminished 7ths. Finally, each half-diminished 7th can lower a single note to lead to the fully diminished 7th at the center of the fifth cross section. The graph shows abstract voice-leading direction: moving one cross section to the left involves raising a voice by semitone; moving one cross section to the right involves lowering a voice by semitone. ⁽¹⁹⁾

Figure 2b. An extension of the tube-shaped seventh-chord map that includes all twelve transpositions of each chord

[2.2] The map in Figure 2a can be extended to include every transposition of a seventh chord; this complete version is shown in Figure 2b. In equal temperament, the tube in Figure 2b is an orbifold: to properly represent it, we would twist the right end a quarter turn clockwise and glue it to the left end. ⁽²⁰⁾ The voice-leading paths form a set of relations, but they cannot form a mathematical function.⁽²¹⁾ In this respect, they are unlike other models used to describe voice leading among seventh chords (such as those presented in and Childs 1998) and do not meet the requirements for forming a generalized interval system.⁽²²⁾ Instead, Figure 2b can be viewed as a cross section of a larger four-dimensional voice-leading space that connects all four-voice chords. The map forms a discrete voice-leading lattice (Tymoczko 2011b, 412-17): one can determine the voice-leading work between any two chords-that is, the total number of semitones that all voices move-by counting the number of segments that it takes to move from one to the other. Voice-leading work provides a useful indicator of how smooth a progression is; it is inversely proportional to how closely related the chords sound (i.e., a low value for voice-leading work indicates a high degree of relation, and vice versa). ⁽²³⁾

Figure 2e. Cross-type progressions

[2.3] Figures 2c and 2d show the possible contrary- and similar-motion progressions, respectively, among the chords on the tube-shaped map.⁽²⁴⁾ These two progressions are created by the combination of two parsimonious motions, but they could also be conceived of as a single pathway involving the displacement of two semitones.⁽²⁵⁾ A contrary-motion progression (Figure 2c) occurs within a cross section and is represented by an arrow moving a quarter-turn clockwise or counterclockwise, or, if major-minor 7ths or half-diminished 7ths are involved, across a pole.⁽²⁶⁾ For major-minor 7ths and half-diminished 7ths, each arrow direction indicates contrary motion of a specific interval class and thus corresponds to a Cx(y) transformation as defined by Childs (1998, 185-187). Contrary motion between two minor 7ths, by contrast, always involves a motion between two ic5s. In a similar-motion progression (Figure 2d), two voices move in the same direction to lead to a different chord type. Similar-motion relations connect major-minor 7ths with half-diminished 7ths (e.g., C7[arrow right]Gø7) or minor 7ths with diminished 7ths (e.g., Cm7[arrow right]Co7). A major-minor 7th or half-diminished 7th chord can use similar motion to move to any chord that is two sections to the right or left on the voice-leading map, except for the chord that is on the opposite pole of the cross section. ⁽²⁷⁾

[2.4] Finally, some songs use cross-type progressions, which change a seventh chord into a triad or vice versa. Some cross-type progressions exploit seventh chords' ability to effect minor-3rd root movement with efficient voice leading; as a result, they are easily modeled with seventh-chord chromatic progressions. ⁽²⁸⁾ An example appears on the upper staff in Figure 2e, which shows a major triad moving to a major-minor 7th whose root is a minor 3rd lower. Two analyses are shown to the right of the progression; each models the voice leading of the progression using the inclusion and exclusion operations, which transform a major triad into the unique major-minor 7th that contains it and vice versa (Hook 2002, 117-18; 2007, 4-5). ⁽²⁹⁾ The first analysis reduces the second chord to a major triad and models the progression as a combination of R and P (i.e., a relative transformation followed by a parallel transformation). The F, which, as a common tone, provides smoothness, disappears from the progression and only reappears as part of an inclusion operation. By contrast, the second analysis treats the first chord as an incomplete major-minor 7th, which moves to the second through a contrary-motion progression that requires less voice-leading work. ⁽³⁰⁾ Tymoczko (2011b, 100) argues for the same interpretation of this progression, citing the F-D7 progression in Nirvana's "Heart-Shaped Box" (1993) as an example. A different inclusion relation (marked with a prime [ [variant prime] ]on Figure 2e) can be defined that maps a major or minor triad onto the unique minor 7th that contains it. Unlike the previous inclusion operation, the relation does not have a single inverse, since a minor 7th contains both a major and a minor triad as a subset. This relation appears in the lower staff on Figure 2e, which shows how a major or minor triad can lead smoothly to a minor 7th through a cross-type progression.

3. Harmonic Schemas for Introducing Chromatic Progressions in Post-Millennial Rock

Table 1. Examples of post-millennial rock songs that use chromatic progressions

[3.0.1] Post-millennial rock songs sometimes introduce chromatic progressions that cannot be easily explained as part of a rock harmonic idiom. These chromatic progressions are often introduced through one of three strategies: (1) in a recurring RN (Roman-numeral) progression, a recurring diatonic progression that can be expressed in Roman numerals is altered to become a chromatic one; (2) in a magic chord, a recurring chord becomes a pivot between normative and non-normative progressions; and (3) in a magic voice leading, a specific voice leading first appears as part of a stylistically normative progression and then reappears, using different chords, in a non-normative progression. Table 1 lists each method of introduction in its column labels. Each column lists some post-millennial rock songs that use each strategy.

[3.0.2] In addition to being categorized by their method of introduction, chromatic progressions can be categorized by one of two functions that they often fulfill: (1) a shuttle or (2) a substitution. Tagg (2009, 173) defines a shuttle as an alternation between two chords that takes place within what he calls "present time"-that is, the span of short-term memory. Generally, both chords have a similar duration and alternate at least twice. ⁽³¹⁾ Often, a shuttle takes up an entire formal unit. A shuttle does not evince the same tension between tonic and non-tonic chords that is found in longer progressions; instead it forms, in Tagg's words, a "place to be" (2009, 171)-that is, a static harmonic backdrop. Some shuttles do not imply a specific key. In these cases they are not so much tonally ambiguous as tonally underdetermined-that is, there is not enough information in the melody and harmony to tilt a listener toward hearing a specific tonic. Tagg cites the verse of the Human League's "Don't You Want Me" (1981) as a non-key-defined shuttle (2009, 192). The section alternates between F-major and G-major triads, which could be reasonably heard as IV-V in C major, VI-VII in A Aeolian, or even VII-I in G Mixolydian.

[3.0.3] In a substitution, a passage is heard as a transformation of a precedent, through one chord or progression replacing another that it resembles. The transformed precedent can be intratextual (a passage from elsewhere in the song), intertextual (a passage from a different song), or virtual (an implied stylistic norm). ⁽³²⁾ Multiple precedents can also pertain to a single passage. Hearing a transformation requires identifying similar features between passage and precedent; as Doll discusses, these features might include the pitch-class content of chords, formal layout and location, melody, and timbre (2009, 27-30).

[3.0.4] The voice-leading map shown in Figure 2b provides one means of ascertaining similarity, because chords that are close on the map will likely have more common tones and move to the next chord with nearly the same voice leading.⁽³³⁾ For example, the tritone substitution, where V⁷ is replaced with "II⁷,"⁽³⁴⁾ exploits the proximity of two polar-related major-minor 7ths, as well as the active tones (and ) that are held invariant.⁽³⁵⁾ Substitutions in rock are not confined to the tritone-based variety; rock has a large set of normative progressions that provide opportunities for other kinds. In addition, while some substitutions preserve the function of the precedent chord, others can alter it, given sufficient similarity in other parameters (Doll 2009, 10-13).

[3.0.5] Table 1 lists these two common functions for chromatic progressions in its row labels. Each row lists songs that use the type of progression identified in the label: the first row lists songs that use chromatic shuttles, and the second row lists songs that use chromatic substitutions. The following sections discuss each example in greater detail.

3.1 Chromatic Progressions Resulting from Transformation of a Recurring RN Progression

Figure 3.1a. Deerhunter, "Earthquake" (2010)

[3.1.1] Some art-rock songs feature a recurring diatonic progression (which can be expressed through Roman numerals) that is altered to become a chromatic one. The Dirty Projectors' "Offspring Are Blank," discussed at the beginning of this article, provides one example, since this song makes several alterations to a II-i Phrygian progression. Deerhunter's "Earthquake" (2010), shown in reduction in Figure 3.1a, alters a virtual precedent of a diatonic shuttle that involves minor-3rd root motion. The precedent is shown above the reduction: a i-III alternation that is inverted to become I-vi in the second half. In the actual song, all the chords are changed to major triads with added sevenths and ninths. The guitar patterns in the upper voices effect a contrary-motion progression that emphasizes parsimonious voice leading in pitch space. The lengths of the chords in each section make the progressions sound like alternations between remote diatonic regions, but a listener attuned to larger time-scales will hear the bass make an ascending and descending arpeggiation through the tonic triad across both sections.

3.2 Chromatic Progressions Resulting from "Magic Chords"

[3.2.1] Some songs feature chords that are marked for memory through frequent repetition and/or unusual voicing.⁽³⁶⁾ I call them (with a request for the reader's indulgence) "magic chords," as they sometimes provide a fulcrum between diatonic and chromatic progressions.⁽³⁷⁾ Western art music from the second half of the nineteenth century provides a rich precedent for the magic-chord technique: as Tymoczko (2011a, 259) and Smith (2009, 63-69) show, many pieces from this era systematically explore the chromatic voice-leading possibilities of a small number of characteristic chords.

(click to enlarge and listen)

[3.2.2] In Mew's "Wheels Over Me" (1997), the magic chord, shown in Figure 3.2a, can be described as EM7sus2. Each time the chord appears, its voicing is nearly identical, with the guitar in a medium-high register. The chord is a memorable element of the song and appears throughout, as the primary chord in the first five seconds and as the first or last chord of every section thereafter. It functions ambiguously, as it could be heard either as IV in Bmajor or VI in G minor, an instance of what Tagg labels "bimodality" (2009, 227-230). The introduction, much as in a nineteenth-century "tonal pairing," juxtaposes both tonics in its upper voices (Krebs 1996, 18; Lewis 1984, 6). As shown in the reduction in Figure 3.2a, the magic chord contains a B-major triad, while its neighboring chord has the root and 5th of a G-minor triad. The verse and second chorus outline the paired tonics in opposite ways: ⁽³⁸⁾ the verse begins with EM7sus2 moving to BM7, suggesting IV-I in B, but ends on an altered G-minor triad, suggesting the relative minor; the second chorus begins in G minor but ends with a Btriad moving to the EM7sus2, suggesting I-IV in the relative major.

Figure 3.2b. Mew, "Wheels Over Me," first chorus

(click to enlarge and listen)

[3.2.3] In the first chorus, by contrast, the magic EM7sus2 becomes the first half of a chromatic shuttle. The section is excerpted and reduced in Figure 3.2b. The upper voices of the guitar's chord, combined with the vocal parts, form Gm7, which then moves by contrary motion to Em7. When the bass line is added below this progression, a chromatic shuttle between EM9 and CM9 results. The arrows in the reduction show how the smooth motion is present in pitch space as well as pitch-class space. The lower voices in the guitar each move by semitone, while the lead and backing vocals exchange motives, transferring the motion from Bto B. As the only section that introduces pitches from outside the two-flat diatonic collection, the first chorus suggests an altered state of being. This state is reinforced by the use of the "short-wave radio" high electronic glissandi, and a sense of stasis created by the consistency of chord type and rapidly strummed guitar. The lyrics also depict an altered or remote state: in a moment of uncharacteristic clarity, they describe a longing for childhood or death. Various homologies between the harmonic progression and the textural and lyrical content might be offered: the two chords in the shuttle might imply two remotely related keys, mirroring the far-flung states (childhood or death) depicted in the lyrics. Or, the harmonic and rhythmic stasis of the shuttle, in contrast with the other sections, can be heard as creating a self-contained, tonally underdetermined section, temporarily removing questions of tonal centricity and indicating a retreat from the other sections' continual alternation between tonics. ⁽³⁹⁾ The section is made poignant by its brevity, as the music quickly returns to the verse or second chorus.

[3.2.4] Grizzly Bear's "I Live with You" (2009) uses a D6 as its magic chord. This chord functions as a tonic, and its status as a point of repose is especially appropriate since the backing guitar that plays throughout is tuned to the same chord on open strings: <D A D FB D>. The verse and chorus both use a harmonic schema that begins with the magic chord, followed by a series of stepwise departures and returns involving the same chord. But, as I argue in the following discussion, the chorus transforms the schema so that it features greater chromaticism and voice-leading disjuncture than the verse.

Figure 3.2c. Grizzly Bear, "I Live with You" (2009), reduction

[3.2.5] Figure 3.2c shows a reduction of the instrumental parts in the first verse and chorus. Notes interpreted as passing or neighboring are enclosed in parentheses. The labeled arrows below the score of the verse show its harmonic schema. After a brief instrumental introduction that presents the chords from the chorus and then features a brief transitional passage for string quartet, verse 1 begins with a series of departures from and returns to the magic chord. The initial departure and return occurs between D6 and E7. This alternation between two chords whose roots are separated by whole step recalls several other rock songs that shuttle between tonic and supertonic in their verse; because of the progression's ease of execution on a guitar, it often suggests a relaxed initial state. ⁽⁴⁰⁾

[3.2.6] Unlike most examples of tonic-supertonic shuttles, both tonic and supertonic in this instance are major triads, implying a Lydian rather than Ionian harmonic progression. While Lydian progressions are rare in rock, I-II is an appropriate descriptor for the verse, since the long duration of the D6, among other contextual factors, asserts D centricity. To be sure, some rock songs alternate between two major triads separated by whole step and later reinterpret these triads as IV and V. An example is REM's "Man on the Moon": the verse alternates between C-major and D-major triads and features a melody that centers on the pitches C and G, creating ambiguity as to whether the chords are IV-V or a Lydian-tinged I-II. The prechorus and chorus of "Man on the Moon" are clearly in G major, encouraging a retrospective interpretation of the verse as a IV-V shuttle. By contrast, interpreting the opening of "I Live With You" as a IV-V progression does not reflect the D centricity of the following sections.

[3.2.7] In spite of the relaxed state suggested by the shuttle, the first verse indicates an underlying tension, since its opening chord is not D6 but rather a dissonant polychord that places an F7 over a D/A pedal. This dissonant initial chord sustains an Athat appeared in the previous string quartet introduction. The dissonant chord does not reappear in the song: as shown in the second system of Figure 3.2c, when the verse progression repeats, the first chord is D6 instead. The opening chord nonetheless indicates an instability that belies the otherwise relaxed character of the opening progression. At the end of the verse, the harmony and instruments effect a brief intensification by moving up to a higher register and transposing the first two chords up a major third to F6 and G7. ⁽⁴¹⁾ But as the verse progression repeats, the tension is dissipated, and the last chord of the verse leads relatively smoothly back to the first-it uses three units of voice-leading work, the same amount required for the opening I⁶-II⁷ alternation. The lyrics in the verse, with lines such as "Return/don't make me beg. . . . They'll try to keep us apart/but yes we can," combined with the relaxed tempo and delivery, allow the lead singer Daniel Rossen to create a persona that gently pleads for a relationship to continue.

(click to enlarge and listen)

[3.2.8] The chorus, also shown in Figure 3.2c, uses the same general harmonic schema as the verse, as shown by the arrows underneath the score. Like the verse, it begins with two alternations between the magic chord and an upper neighbor, continues with a period of intensification through upward transposition, and concludes with a return to the magic chord. The only difference between the schemas is that in the chorus, only one chord is involved in the upward transposition rather than two. But in spite of its harmonic similarity, the instrumental parts are transformed in mood and character, and a disjuncture becomes evident between the accompaniment and the lead singer's persona. The accompaniment fulfills what Moore (2012, 191) calls an interventionist role: it creates an environment that goes "further than. . .the lyric by amplifying what it signifies." Each statement of the chorus adds distorted instruments whose rhythms are increasingly askew from the primary beat. As shown in the transcription in Figure 3.2d, the second chorus adds manic high-register synthesizer arpeggiations whose rhythms are not in sync with the rest of band, and which begin before each downbeat. In m. 4, the drums play a fill that becomes so spastic that it puts a kick-drum and hi hat, which normally occur on the beat, a sextuplet later than expected. The chorus thus enacts the fissure of the relationship that the persona fears. This texture that is on the brink of coming apart at the seams contrasts with Rossen's relaxed vocal, which, although it moves to a high register, maintains a mellifluous tone, refraining from straining the vocal cords, and continues singing slightly behind the beat, as shown by the rhythms in Figure 3.2d. ⁽⁴²⁾ Although the vague lyrics in the chorus make it difficult to identify the persona's attitude precisely-is it nonchalance or a gentle pleading?-it is clearly incommensurate with the world falling apart around him.

[3.2.9] The harmonic progression in the chorus amplifies the chaotic environment created by the accompanimental texture. This section exclusively uses chords of set-class [0357], the same quality as the magic chord, but the first two chords are D6 and Dm7. Unlike in the verse, this opening shuttle does not fit in a single diatonic collection. Given the length of the chords and their repetition, some listeners may even hear an alternation between remotely related keys. The Dm7 includes F, allowing the lead vocal to hold this pitch over both chords, and it also includes the pitch A, as if making a payment on the promissory note made by the first dissonant chord containing the same pitch in verse 1 (see Figure 3.2c). At the end of the chorus, Dm7 moves up by semitone to Em7 as part of the "intensification" portion of the harmonic schema, so that the former chord can be retrospectively heard as a chromatic passing chord. As the chorus leads to the repetition of the verse, Em7 leads back to D6, the magic chord.

[3.2.10] The chorus, in summary, alters the character of the verse by switching from soft to extremely loud, from sparse to dense, from an initial diatonic progression to an entirely chromatic one, and from alternation between minor 7ths and major-minor 7ths to obsessive use of minor 7ths. To further understand the effect of the minor 7ths used in the chorus, it is helpful to imagine counterfactual reharmonizations of the opening phrase. Figure 3.2e shows three harmonizations of the opening two measures of the chorus. In all of them, the accompaniment alternates between two different minor 7ths, and the second chord is consonant with the vocal's F. But in harmonization (1), the first and second chords both belong to the D-major diatonic collection. In this respect, they do not create a sharp contrast with the verse, which also opens with a diatonic progression, and they give the impression of a common shuttle progression such as i ⁷-iv⁷ or IV^add6-I^add6, lacking the jarring effect created by a shuttle between non-diatonically related chords. Harmonization (2) alternates between a Bm7 and a Gm7. Unlike harmonization (1), the chords are not diatonically related. But the chords are relatively smoothly connected-they relate by a contrary-motion progression and have two notes in common. The lyrics state that "you brought us this far," but in terms of voice-leading work, the two chords do not bring us very far. By contrast, harmonization (3), which is the actual version used in the song, juxtaposes two chords that have only one tone in common (the vocal's F) and require more voice-leading work: the D and A slide up by semitone, and the B moves up to C. These two chords, in contrast to harmonization (2), do bring us far.

[3.2.11] The role of harmony and abstract voice leading in the chorus is, admittedly, subtler than the obvious contrast created by the change in volume and texture. Nonetheless, the effect of the harmonies used in the chorus is distinct from those of the other potential harmonizations. The voice-leading map in Figure 3.2f shows that the entire chorus, save for its final chord, uses progressions that are characteristic of the initial one: it connects minor 7ths that do not share a diatonic collection, that connect by ascending motion in idealized voice-leading space, ⁽⁴³⁾ and that involve four units of voice-leading work, the maximal amount of work connecting two minor 7ths.

3.3. Chromatic Progressions Resulting from "Magic Voice Leading"

[3.3.1] Other songs incorporate chromatic progressions by first introducing a voice-leading motion as part of a stylistically normative progression, and then revisiting the same voice leading, using different chords, as part of a non-normative progression. I call the voice-leading motions that engender the unusual progressions (with another for of the reader's indulgence) "magic voice leadings." They can be construed either as a direction on the voice-leading map (that is, as a specific motion between interval classes) or as a motion between specific pitch classes.

[3.3.2] In the refrain of Radiohead's "2+2=5" (2003), the harmonization of a chromatically descending bass line introduces characteristic "magic" voice-leading motions. The song's terminal climax isolates and combines these voice-leading motions to form a new chromatic shuttle. ⁽⁴⁴⁾ The chromatic shuttle, as will be demonstrated, brings with it a transformation in affect and texture: the new progression removes the cues for melancholy and eeriness that were characteristic of the opening music, and replaces them with a depiction of anger and high arousal.

[3.3.3] Figure 3.3a shows a reduction of the verse/refrain. The guitar is shown on the lower staff, and the two vocal parts are shown on the upper staff-the lead vocal is in large noteheads, and the backing vocal is in small noteheads. The bassist does not play in the section. In mm. 1-11, the vocals and guitar use narrow melodic motion and feature several vertical dissonances. These elements amplify the melancholy state suggested by the minor key, bare soundscape, and lyrics enjoining retreat from the world. ⁽⁴⁵⁾ In mm. 3, 7, and 11, where the harmony changes from i to V⁶, a tonic pedal is sustained in an inner voice of the guitar part, creating a dissonant minor ninth with the leading tone in the bass. A dotted slur in the reduction connects the sustained notes. Over the same passage, the lead vocal outlines the chromatic double-neighbor figure C-D-C-B-C, using a minimal vocal range. The figure creates dissonances with the backing guitar: the Dcreates another minor ninth with C, and the Bcreates a major 7th.

[3.3.4] In mm. 9-18, a chromatically descending line from to appears in the lower voices. Classically-trained listeners might also hear the chromatic descent from to as supporting the earlier cues for melancholy, as it is reminiscent of the "lament bass," which frequently appears in minor-key pieces that suggest sadness or lament. ⁽⁴⁶⁾ The chromatic descent begins in the lowest voice and is then transferred to an inner voice: the lines in the figure trace the descent. The descent's registral displacement arises in part from the guitar's "drop-D" tuning, which makes playing the low C impossible. ⁽⁴⁷⁾ On the album track, the guitar skips over Din verse 1 but presents the full descent in verse 2.

[3.3.5] Beginning in m. 13, the backing vocal sings a chromatically ascending line, connected by solid lines in Figure 3.3a, which counterpoints the guitar's descent. In mm. 13-16, the vertical minor 9ths and major 7ths that characterized the first part of the verse temporarily disappear, yielding instead pure triads and major-minor 7th chords. The change to relative consonance, combined with the motion to a melodic climax, draw attention to the song's title refrain, "two and two always makes a five."

[3.3.6] The two chromatic lines in the bass and backing vocal yield several contrary-motion chromatic progressions, departing from the tonic-dominant polarity in the first half of the verse and reflecting the mathematical impossibility of the refrain. In mm. 13-15 F7 moves, via ic2[arrow right]ic4 (E/F to D/F), to D7. In mm. 36-37, a G-minor triad moves, via ic5[arrow right]ic5 (D/G-D/A), to an inverted D-major triad with added 11 (i.e., G, labeled as G ^ø9/7 with a missing 3rd above the score).⁽⁴⁸⁾ The members of the D-major triad all descend by semitone to the dominant; thus, m. 17 continues the pre-dominant function of m. 16.⁽⁴⁹⁾ The G3 in the guitar recalls the tonic pedal from the first part of the verse and reintroduces the vertical minor 9^th between guitar and vocals.⁽⁵⁰⁾

[3.3.7] The chromatic voice-leading motions introduced in the verse reappear in the song's terminal climax. The section represents a transformation in affect in comparison with the verse: what was melancholy swells into a state of high arousal, suggesting grief or anger. The piling on of dissonances and snaky melodic lines characteristic of the verse disappear-instead the chords are presented without added dissonances and the melodic line makes wide leaps. In addition, distortion is added to the guitars, creating slightly indigestible timbres (Blake 2012). Osborn identifies vocal high points, loudness, and the repetition of a short, memorable figure as markers of terminal climaxes in rock music (2013, 27-28). In "2+2=5," the climactic status of the final section is further underscored through maximal chromatic intensity-that is, through presenting a single voice-leading motion that summarizes the previous chromatic progressions and contains the greatest amount of chromatic half steps. The climax, shown in reduction in Figure 3.3b, shuttles between what could be labeled ivand a V ⁷/V. While the two chords point to V, they never actually resolve there, and their repeated alternation detracts from their tendency toward resolution. The use of contextually unstable chords (a major-minor 7th and inverted minor 7th) lends this section an unstable quality, reinforcing its climactic status. As shown in the analysis above the staff in Figure 3.3b, the progression in the climax combines the characteristics of the two chromatic progressions from the end of the verse section. The ic2 in Bm7 (A/B) moves by contrary motion to an ic4 (G/B), and the ic5[arrow right]ic5 contrary-motion from the verse (D/G-D/A) is reversed, using the identical pitch classes, to become D/A-D/G.

[3.3.8] Grizzly Bear's "What's Wrong" (2012) introduces two semitonal voice leadings in its verse-B-Band E-F-to link chords representing competing pitch centers. In the interverse,⁽⁵¹⁾ the voice leadings are fused into a chromatic contrary-motion progression that underscores the tonal ambiguity of the entire song. The ambiguity provides a fitting counterpart to the hesitant, searching quality of the vocals: they contain the repeated line "please make your mind up," which is sung slightly behind the beat, in a comparatively soft position in the recording mix, and from different stereo locations, as if suggesting personae who are at a distance from the listener, lost within the intricate texture created by the backing instruments. ⁽⁵²⁾

[3.3.9] The introductory riff, shown in Figure 3.3c, presents tonal ambiguities that are explored throughout the song. The riff uses notes from the natural diatonic collection, but has contextual reinforcements that suggest F, E, and A as potential tonal centers (Capuzzo 2009, 160). A synthesizer sustains an F-major triad in the upper register. The guitar's repeated pattern has E as its lowest note and outlines the 5th B-E, but it also contains the 4th A-E. The following verse and chorus, in reduction in Figure 3.3d, assert each of these pitch centers in turn. The verse alternates between Em7 and F major, representing two of the potential tonal centers asserted in the introductory riff. The chorus interprets the verse's last chord as VI and slips into A minor, visiting the other tonal center suggested.

[3.3.10] The verse introduces the song's two "magic" voice-leading motions: B-Band E-F, shown with red arrows in Figure 3.3d. The progressions containing them are highlighted with dotted boxes. In the verse, the semitone B-Bprovides a chromatic passing motion to the A in the third chord. The Bis harmonized with a B-major triad (embellished with a 6-5 suspension). The use of Em7, rather than a simple E-minor triad, allows for a smooth progression to the B-major triad: as in the cross-type progression shown in Figure 2e, the 7th of the first chord is held as a common tone. The dotted arrow in the verse shows a large-scale semitonal ascent in the bass line from E to F.

[3.3.11] In the interverse (shown on the third system in Figure 3.3d), the previous tonal ambiguity is briefly put in abeyance through a stable Dm7-Gm7 alternation, suggesting i⁷-iv⁷ in D minor. The new progression subtly
