An in-depth walkthrough of jazz harmonic regions and the mDecks map inspector, covering tonic/subdominant/dominant roles and common chromatic devices.
This lesson explains how the map inspector visualizes harmonic function—tonic, subdominant, and dominant—and demonstrates typical movement patterns and tension/release relationships. It covers practical examples including Neapolitan sixths, secondary dominants (ii–V), two‑fives, augmented sixth variants, and cadential/passing diminished options. The walkthrough also shows how to filter chords by diatonic scales, minors, and secondary functions to quickly find harmonic options within a key.
