Three levels of application
- Only the approach chord (the most common): replace the dominant with its image and leave the tonic as it is. G7 → C becomes Fm6 → C (or Dø7 → C). Effect: minor plagal cadence, soft and cinematic.
- A whole section mirrored (verse, bridge, special): you create a "polarity" contrast with recognizable material, like a theme that returns in negative.
- Melody and harmony together: you mirror everything, including the vocal line; it works as a compositional tool for generating ideas, which you then refine by ear.
Translated progressions (C major, axis E/Eb)
| Original | Degrees | Negative | Degrees |
|---|---|---|---|
| C G Am F | I V vi IV | Cm Fm Eb Gm | i iv bIII v |
| C Am Dm G | I vi ii V | Cm Eb Bb Fm | i bIII bVII iv |
| Dm7 G7 Cmaj7 | ii7 V7 Imaj7 | Gm7 Dø7 Abmaj7 | v7 iiø7 bVImaj7 |
| F G Em Am | IV V iii vi | Gm Fm Ab Eb | v iv bVI bIII |
| C7 F7 C7 G7 (blues) | I7 IV7 I7 V7 | Cm6 Gm6 Cm6 Fm6 | i6 v6 i6 iv6 |
Notice the last row: the blues in negative becomes a world of minor sixth chords, very close to the "noir" color and to minor swing.
Hybrid versions (the most musical)
- ii–V–I with negative dominant: Dm7 – Fm6 – Cmaj7. The bass D–F–C works, and the Fm6 contains Ab, which falls to G, and D, which rises to E: perfect voice leading.
- Turnaround: Cmaj7 – Am7 – Dm7 – G7 becomes Cmaj7 – Am7 – Dm7 – Bb9 (image of G9): the backdoor dominant that "arrives from below."
- Double plagal: C – F – Fm6 – C (IV – iv6 – I), typical of gospel and ballads.
- Complete negative cadence: Gm7 – Dø7 – Cm: minor resolution without a leading tone, useful for suspended endings.
Application to melody
A bass line or synth riff in C: C – E – G – A – G – E. Image: G – Eb – C – Bb – C – Eb. The contour is inverted and the mode is minor; layered over a C minor pad, it becomes a variation of the original riff, great for a second verse or an alternate drop.
Strategies for not losing the center
- Keep the tonic and the bass on structural points (start of a phrase, cadence).
- Mirror the passing and approach chords.
- Use the mapping to choose the guide tones: the images of B and F (Ab and D) are the "negative leading tones."
- Check the avoid notes: if the melody holds B over Fm6, a major-seventh dissonance arises that can be beautiful but must be intentional.
Listening examples and references
- Steve Coleman, albums from the 1980s–90s with M-Base: progressions built on symmetrical movements; the essay Symmetrical Movement Concept explains the method.
- Jacob Collier: in his masterclasses he demonstrates how the minor plagal cadence produces the same sense of "arrival" as an authentic cadence; in his vocal harmonizations he often uses the minor subdominant.
- Classic pop: In My Life (Beatles) and Creep (Radiohead) contain the IV–iv–I move, that is, the dominant replaced by its negative image.
Practical exercise (20 minutes)
- Take one of your own I–V–vi–IV progressions.
- Write the complete negative version (Cm Fm Eb Gm if you are in C).
- Build a two-part song: verse in negative, chorus original. The shift from minor to major creates a strong emotional opening.
- Finally, try the hybrid version: keep I and vi, mirror only V and IV (C Fm Am Gm). Listen to how the vi between two minor chords changes color.
Common mistakes
- Mirroring the bass blindly and ending up with unstable inversions.
- Forgetting that the arrival note of a melody changes (C becomes G): the phrase no longer closes.
- Using it as a "magic" shortcut: it is an idea generator; then the ear decides.
