Workshop 17 — “All of Me”: Secondary Dominants Everywhere, Turning a Simple Tune into a Functional-Harmony Laboratory

This workshop is ideal for consolidating secondary dominants.

“All of Me” sounds approachable, but harmonically it gives you repeated examples of:

The central lesson is:

Secondary dominants stop feeling like exceptions once you hear them as temporary arrows pointing to ordinary diatonic chords.

We’ll work conceptually in C major.
