Key ideas in Chord Progressions and Harmonic Motion
- Good voice leading preserves melodic smoothness by shifting voices by steps.
- Moving block shapes causes disruptive parallel leaps across all voices.
- Retaining shared pitches grounds harmony and cushions chord shifts.
- Moving every voice unnecessarily breaks the acoustic thread between chords.
- The 3rd and 7th form guide tones that define chord identity and motion.
- Roots and 5ths offer tonal stability but contribute little forward pull.
- A half-step shift creates maximum harmonic tension and release.
- Semitone pull like the leading tone to tonic drives musical resolution.
- Inversions place the 3rd or 5th in the bass to step between root notes.
- Inverted chords smooth the bass contour without altering the underlying key.
- A deceptive cadence diverts a V chord into a vi chord instead of resolving to I
- Landing on the submediant vi prolongs harmonic momentum by denying tonic closure
- The surprise works because vi shares two common tones with the expected I tonic
- Plagal cadences move IV to I without using scale degree seven as a leading tone
- The IV to I movement creates a gentler, hymn-like resting point than a V to I resolution
- The tonic pitch is held as a shared common tone between IV and I
