- Utilization of the tritone substitute dominant (Db7) resolving to the tonic (C6) facilitates a sophisticated chromatic bass descent.
- Frequent use of the “backdoor” dominant (Ab7 to C6) injects a blues-inflected, flattened-sixth color characteristic of the stride era.
- The progression employs a classic VI7 - ii7 - V7 turnaround (A7 - Dm7 - G7) to reinforce the C major tonal center.
- Movement through the subdominant F7 toward Bm7b5 suggests a brief shift toward the relative minor (A minor) through a ii-V framework.
Improvisation Focus: Guide-tone targeting to navigate the frequent chromatic substitutions and non-diatonic dominant chords.
Difficulty Rating: 3/5: While the C major foundation is accessible, the constant shift between diatonic chords and chromatic substitutes requires precise harmonic awareness.
