What is Modal Interchange?

Modal Interchange is a harmonic technique in which chords are borrowed from parallel modes or scales that share the same root note. It is known for adding color and variation to otherwise standard chord progressions.

The style typically involves taking chords from modes such as the parallel minor or major (for example, borrowing from C minor while in C major), introducing notes outside the original key.

Modal Interchange emphasizes contrast and tonal color, allowing composers to create unexpected emotional shifts without fully changing the key.

The music often uses borrowed chords to add tension, richness, or mood changes within a progression while maintaining a clear tonal center.

Today, Modal Interchange is widely used in film scoring, pop, rock, and jazz, valued for its ability to expand harmonic expression while keeping progressions accessible and cohesive.
