Explore a practical dominant-chord substitution using the symmetric diminished (half‑whole) scale to create rich b9/#9/#11 colors over V chords.
This lesson demonstrates a versatile dominant substitution—turning dominants into 7b9 chords and using the symmetric diminished scale—to generate both b9 and #9 tensions while preserving the 13. Using examples from Misty, Ariel & Adam show how the substitution works in 2–5 progressions and highlight useful upper‑structure triads (like A major over Eb7) to expand your voicing palette. Playable scale choices, voicings, and musical examples are provided so you can hear and apply the colors in context. Supplementary PDF material is available to reinforce the concepts and exercises.
