Workshop 54 — “Mercy, Mercy, Mercy”: Soul-Jazz Harmony, Gospel Cadences, Backbeat Feel, Repeated Hooks, and Making Simple Chords Sound Warm Instead of Plain

After Workshop 53’s extreme minimalism, the next step is to keep the harmony relatively simple but make the voicing, groove, and emotional pacing do more of the work.

A “Mercy, Mercy, Mercy”-type environment is ideal for this because the music draws power from:

The main question is:

The central lesson is:
