Harmonic Highlights:
- Prominent use of diatonic II-V-I progressions (Cm7-F7-Bbmaj7) firmly establishing the Bb major key.
- Strong harmonic movement to the subdominant via a II-V-I progression (Fm7-Bb7-Ebmaj7), enriching the tonal landscape.
- Integration of common jazz color chords like the minor iv (Ebm7) leading to the tonic, and the Db07 diminished chord functioning as a substitute for V7b9 or resolving to the ii-V.
Improvisation Focus: Bb Major scale and its related diatonic modes (Dorian for ii, Mixolydian for V) for navigating the core progressions.
Difficulty Rating: 3 (Intermediate). Requires understanding of diatonic functional harmony, secondary dominants, and characteristic jazz color chords for effective improvisation.
