Substitute Chord – Definition
A substitute chord is a chord that replaces another chord while preserving a similar harmonic function. Chord substitutions are used to create variety, richer harmony, and smoother chord progressions.
What is a Substitute Chord?
Some substitute chords share several notes with the original chord, while others perform the same harmonic function in a different way. Common examples include relative major and minor chords, secondary dominants, and tritone substitutions.
Chord substitution is an important technique in jazz, pop, gospel, and contemporary arranging.
Why are Substitute Chords useful for pianists?
Learning chord substitutions allows pianists to create more interesting accompaniments without changing the melody. Simple substitutions can add color, movement, and sophistication while preserving the overall character of a song.
Understanding substitute chords also strengthens harmonic awareness and provides more creative options for arranging and improvisation.
