Harmonic Highlights
- The prominent Ab07 functioning as vii°7/ii, a chromatic diminished chord leading to Gm7.
- Frequent tonicization of the subdominant via ii-V-I (Cm7-F7-Bbmaj7).
- The characteristic Bbm7-Eb7-Ab6 progression (iv-bVII-bIII) providing rich ‘backdoor’ harmony.
- Strong resolution to the tonic using G7b9 (V7/V) leading into the V7-I cadence.
Improvisation Focus Navigating ii-V-I progressions and their common alterations across tonicizations.
Difficulty Rating 3 (Intermediate). The chart combines standard ii-V-I movements with chromatic diminished chords and extended tonicizations, requiring a solid understanding of common jazz substitutions.
