Workshop 36 — “Caravan”: Phrygian-Dominant Color, Dominant Pedals, Harmonic Minor, and When a Dominant Chord Becomes the Home Sound

This workshop introduces a wonderfully strange harmonic situation:

What happens when a dominant-type chord lasts so long that it stops feeling like a chord waiting to resolve and starts feeling like the tonal center itself?

That is one of the defining sounds behind “Caravan.”

We’ll use a conceptual C-minor / G-dominant framework rather than reproduce the complete copyrighted chart.

The main lessons are:

The central lesson is:

A dominant chord does not always mean “resolve now.” Sometimes you can build an entire musical world inside the dominant itself.
