- Each mode emphasizes different scale degrees
- Modal harmony is built around these centers
- Understanding centers helps with improvisation
Modal Interchange
Borrowing chords from parallel modes to add color and interest.
- Enriches harmonic palette
- Creates interesting contrasts
- Common in contemporary music
- Useful for reharmonization
Modal Harmony
The characteristic chord progressions and harmonies associated with each mode.
