Secondary Dominants

Identify secondary dominant chords and understand how they create motion.

Instructions

1. Set Level 5, key of C Major on Guitar.
2. Select D7 chord. An amber badge appears: "V7/V" — D7 is the dominant of G (V).
3. This means D7 wants to resolve to G. It's "borrowing" from the key of G to create tension.
4. Select A7. Badge shows "V7/ii" — A7 is the dominant of Dm (ii).
5. Select E7. Badge shows "V7/vi" — E7 resolves to Am (vi).
6. Secondary dominants add color and movement. They're not in the key, but they serve a function.
