Harmonic Highlights:
- The recurring Am7b5-D7b9-Gm6 progression establishes a strong G minor tonic via a classic ii-V-i.
- Ab7#11 functions as a tritone substitution for D7 (V7 of Gm), featuring a prominent #11 for altered dominant tension.
- Eb7 acts as a backdoor dominant to Ab (IVmaj), creating non-functional tension before the tritone substitution.
- Secondary dominant movements, such as G7-C7-F7, build strong harmonic momentum towards the relative major (Bbmaj7).
Improvisation Focus: Accurately outlining the minor ii-V-i progression using G harmonic and melodic minor scales.
Difficulty Rating: 3 (Intermediate). Features clear minor ii-V-i progressions and common substitutions, demanding harmonic flexibility for non-diatonic dominant resolution.
