Harmonic Highlights:
- Clear and foundational diatonic II-V-I progressions in Bb major establish the primary key center.
- Prominent secondary dominant function, exemplified by the Am7-D7 movement resolving to the Gm minor chord.
- Temporary tonicization of the V chord (F) is achieved through a iiø7-V7 progression (Gm7b5-C7 leading to Fmaj7).
- Inclusion of altered dominant harmonies (F7b9, C7#11) and the unique Gm/maj7 sonority adds significant chromatic color and harmonic depth.
Improvisation Focus: Melodic minor applications over altered dominant and tonic minor chords.
Difficulty Rating: 4 (Advanced Intermediate). The combination of frequent chord changes, secondary dominants, and advanced altered chords demands a sophisticated understanding of scale application beyond basic diatonicism.
