Esperanza Spalding‘s “12 Little Spells” is like a game for your ears; the harmony is always shifting and arrangements as well! You constantly slip and try to hold on to something you recognize, but it keeps going, with the drums, the bass, or the chords… You’re a bit lost, but it’s pleasant, too.
In modern music, this is an extreme example of how artists play with harmonies and modulations. A well-known example is the vocal introduction of this Kate Bush song. The way she walks inside the song is incredible – as if it were a “multi-room” song:
So what? This IS what I like in music. Modulations. Sometimes it’s very obvious and “catchy”, like in The Riddle. Some parts of the song are very “chord simple”, but the transitions are wild, and the break is silly. It modulates like crazy!
This is what I love. Sometimes, the craftiness is deeply hidden in the music (Depeche Mode, Röyksopp), sometimes it’s pretty bold and wild (Genesis, Yes), even in quiet music (John Barry!). I love the sudden, clear modulations that you find in Klaus Schulze and his “stairs of music” (it’s often just a transposition), or in Pat Metheny’s music. Some are kings, they just like it boldly (Joni Mitchell, Stevie Wonder)
Clearly, sometimes you wonder if modulating is just the purpose of the song (like here in Again and Again):
In classical music, it’s all the same. I love it when it’s in the fabric of music (Brahms, Puccini) or bolder like Prokofiev or Chostakovitch.
Now here’s an article about “types of modulations” I asked ChatGPT to write (my English is very poor and my personal harmonic skills are meh, so I couldn’t do it myself):
Types of modulation and examples drawn from selected popular and film composers
Introduction — why classify modulations in contemporary music
Modulation (a shift of tonal center or key) is a fundamental expressive device. In contemporary, popular and film musics it appears under many guises: abrupt “brutal” key changes used for dramatic shock; smooth “invisible” modulations that relocate a tonal center without the listener’s conscious detection; common-tone or mediant shifts that provide colour rather than functional reorientation; and modulatory techniques that generate prolonged tension (pedal points, drones, slowly shifting ambiances). Understanding these categories clarifies how different artists use modulation as an expressive resource. Foundational expositions and practical categorizations (pivot-chord, common-tone, direct/phrase modulation, enharmonic/pivotal re-spelling, chromatic mediant, etc.) are available in modern theory literature.
Taxonomy of modulations (with musical examples)
A —
Brutal / direct modulations (sudden, no pivot preparation)
Definition & effect: the music jumps to a new key without a shared pivot chord or gradual harmonic preparation; effect is immediate change, dramatic acceleration or heightened urgency. The classical term is phrase modulation or direct modulation.
Examples & artists
- Nik Kershaw (1980s pop): many 1980s synth-pop arrangements favour noticeable, assertive key shifts between sections to lift choruses or to maintain pop momentum. Analyses and listeners’ breakdowns of Kershaw’s more complex songs point to multiple, sometimes abrupt sectional shifts typical of the era’s production aesthetics.
- The Beatles: several Beatles songs employ abrupt shifts (for example, sudden modal/tonal shifts between verse and middle-8) to contrast narrative fragments; A Day in the Life and other late-period Beatles tracks show fragmentation and sudden tonal refocusing. These are often arranged as dramatic sectional contrasts rather than smooth classical modulations.
B —
Invisible / pivot-chord modulations (smooth, functionally camouflaged)
Definition & effect: using a chord common to both keys (pivot) or a diatonic chord that functions in both places to create a gradual, almost seamless transition. This is the typical “invisible” modulation used in theatre and film to preserve narrative continuity while changing key.
Examples & artists
- John Barry (film music): film composers who write extended orchestral cues often prefer pivot-based modulations or common-tone devices so the music can shift emotional register without jolting the viewer. John Barry’s Bond scores routinely use functional pivots and orchestral re-voicing to move between keys while maintaining dramatic flow.
- Pat Metheny (jazz-informed harmony): Metheny frequently modulates through ii–V–I sequences and smooth voice-leading; his approach often masks modulations inside sophisticated but seamless jazz functional progressions, enabling melodic continuity across tonal areas.
C —
Mediant / chromatic-third relationships (colouristic shifts)
Definition & effect: moving to keys a third apart (chromatic mediant) — e.g. C major → A♭ major — produces striking color without the functional gravity of dominant-based modulations. Used for tonal colouring rather than conventional cadence.
Examples & artists
- Joni Mitchell: Joni’s dense palette arises from alternate tunings and modal shifts that produce chordal relationships not easily expressed in standard tuning; these tunings and voice-leading choices create many color shifts akin to mediant relations and modal interchanges used for expressive colour. Her later jazz influences deepen the use of third-relations and modal shifts.
- Kate Bush: analyses of Kate Bush point to ambiguous tonal centers, chromatic neighbor motion and mediant-like harmonic transformations that contribute to her eerie, shifting soundscapes — a colouristic modulation rather than a classical functional key change.
D —
Common-tone and enharmonic modulations (sustained pitch as bridge; re-spelling pivot)
Definition & effect: hold a single pitch present in both keys (common-tone) or re-spell a chord enharmonically to reinterpret its function and thereby pivot to a distant key. These are favoured for elegant, sometimes theatrical changes.
Examples & artists
- The Beatles: use of common tones or modal borrowing to connect sections; Paul McCartney in particular often uses subtle common-tone lines to reframe harmonic function. Penny Lane and Here, There and Everywhere demonstrate careful voice-leading and chromatic pivoting.
E —
Prolonged tension through modal/dronal shifting (slow spectral or ambient modulation)
Definition & effect: rather than an immediate key change, the music sustains a pedal or drone while slowly altering colours, resulting in a sense of unfolding modulation or evolving tonality. Common in ambient, electronic and some progressive rock contexts.
Examples & artists
- Klaus Schulze (electronic ambient / krautrock): Schulze’s work frequently creates slow, expansive textures built on drones and evolving synth timbres; the sense of modulation comes from timbral filtering and added pitch content rather than conventional pivot chords. His technique emphasizes process and gradual shift.
- Röyksopp: in modern electronic music, modules of layered synths and subtle pitch/interval additions produce perceived tonality shifts; tracks such as those on Melody A.M. rely on textural layering and modal colouring rather than explicit classical modulations.
F —
Modulation by arrangement and orchestration (film & theatre practice)
Definition & effect: orchestration itself can imply or realize a modulation: re-voicing, doubling, and reassigning melodic material across sections can make a modulation feel more or less dramatic. Film composers exploit orchestral color to make small harmonic shifts read as major narrative events.
Examples & artists
- John Barry: his Bond work shows how orchestral timbre and layered harmonic textures can perform the work of a modulation — the listener experiences tonal shift partly because of timbral re-contextualization rather than a simple harmonic pivot.
G —
Jazz/“inside–outside” modulations and extended tonal movement
Definition & effect: jazz idioms introduce modulations by extended II–V cycles, modal interchange and deliberate “outside” playing that temporarily undermines the home key; the result can be fleeting tonal excursions or sustained re-centering.
Examples & artists
- Pat Metheny: blends “inside” tonal phrases with progressively “outside” harmonic choices; his compositions and improvisations often imply modulations through modal interchange, extended dominant chains, and sophisticated voice-leading rather than explicit abrupt key changes.
H —
Sectional/episodic modulation (progressive rock / long-form structures)
Definition & effect: in long, suite-like forms, entire sections may inhabit different tonal regions; transitions may be abrupt or gradual, but the architecture of the piece treats modulation as structural segmentation.
Examples & artists
- Mike Oldfield: Tubular Bells and similar long-form works are built from episodic sections that reframe tonal centers; modulation functions at the level of formal design — sections move, return, and contrast through a series of tonal environments.
I —
Pop harmonic strategies: lift-modulation (classic “truck-up”)
Definition & effect: a well-known pop device is an upward semitone or whole-tone modulation for the last chorus to heighten excitement — often deployed in commercial pop, musical theatre finales, and film songs. This is a form of direct modulation used to amplify the climactic section.
Examples & artists
- Stevie Wonder: while not always using the classic “semitione lift” as a gimmick, Wonder’s harmonic language uses chromatic passing chords, secondary dominants and blues-derived alterations which can produce rising dramatic moments; his harmonic craft often disguises modulation within rich extensions. Analyses of Wonder’s writing show frequent chromatic neighbors and altered dominants rather than naive direct key lifts.
Short comparative observations (how these artists differ in modality/modulation approach)
- Texture vs. function: electronic and ambient artists (Klaus Schulze, Röyksopp) often “modulate” by timbre and additive pitch content; their shifts are spectral and processual. Classical/pop/film writers (John Barry, Beatles, some Broadway composers) typically employ functional pivots or clear, theatrical key changes.
- Instrumental technique as a cause: Joni Mitchell’s extensive use of alternate guitar tunings produces harmonic possibilities (open clusters, unusual voicings) that enable coloristic shifts and mediant relationships not easily achieved on standard tuning. This is an example where an instrumental technique generates frequent modal/harmonic surprises.
- Pop production aesthetics: 1980s pop (Nik Kershaw et al.) and later pop/rock often use multiple abrupt sectional key shifts as a production tool to maintain momentum or create punchy contrast; these changes are frequently arranged for effect rather than as classical functional modulation.
Conclusion — practical takeaways for a listener or analyst
- Classify first, analyze second: listen for whether a change is accomplished by pivot chords, held common tones, an enharmonic re-spelling, abrupt phrase shift, or by textural/timbral processes — the category suggests the composer’s intention (dramatic shock, seamless narrative, colouristic re-framing, or ambient evolution).
- Look beyond the chord label: many modern practitioners create the perception of modulation by orchestration, tunings, or surface voice-leading rather than by textbook pivot-chord sequences. This is true across the roster you gave (from Schulze’s drones to Mitchell’s tunings to Barry’s orchestration).
- Use targeted listening examples: for practical study, compare a direct pop lift (an 80s chorus key change), a Beatles mid-section pivot, a Joni Mitchell guitar passage (alternate tuning) and a Schulze ambient drone — the contrast makes clear the taxonomy above.
