Tritone Substitution — Music Theory Guide
Tritone substitution replaces a dominant chord with another a tritone away — adding chromatic flavor.
Tritone Substitution is a key concept in music theory and composition. Tritone substitution is a jazz technique where you replace a dominant 7th chord with another dominant 7th chord whose root is a tritone away. For example, replacing G7 with D♭7 (both resolve smoothly to C). The two chords share the same tritone interval.
Producers, composers, and songwriters use Tritone Substitution to add color, tension, or movement to their music. The technique works because it shifts what your ear expects — and shifting expectations is the engine of musical interest. Whether you are writing a pop song, a film score, or a beat, Tritone Substitution gives you a specific tool for specific moments.
