Modal Interchange: Expanding Harmonic Vocabulary
Modal interchange involves borrowing chords from parallel modes or keys to enrich harmonic progressions. This technique allows composers to add color and emotional nuance, making their music more expressive and dynamic.
Common Modal Interchange Techniques
- Borrowing the iv chord from the parallel minor in a major key
