Step-by-step reharmonization of "Amazing Grace" using Mapping Tonal Harmony Pro, covering substitutions, secondary dominants, tritone subs, inversions, and cadences.
A practical tutorial that walks through a complete reharmonization of "Amazing Grace," demonstrating how to use Mapping Tonal Harmony Pro to visualize and create harmonic journeys. Ariel and Adam show concrete techniques — chord extensions, secondary dominants, ii–V interpolations, subV/tritone substitutions, deceptive cadences, I64 usage, and voice-leading/inversion tricks — and explain how each choice alters color and bass motion. The lesson emphasizes how to apply these tools in any key and offers variations you can try while following along.
