Secondary Dominants — Music Theory Guide

Secondary Dominants is a key concept in music theory and composition. Secondary dominants are dominant chords that resolve to a chord other than the tonic. For example, in C major, D7 is the V7 of G (V/V), and it resolves smoothly to G major. Using V7/ii, V7/iii, V7/IV, etc., adds harmonic interest and forward motion.

Producers, composers, and songwriters use Secondary Dominants 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, Secondary Dominants gives you a specific tool for specific moments.
