- Frequent use of the diatonic ii-V-I progression (Cm7-F7-Bbmaj7) as the primary cadential device.
- Tonicization of the relative minor (Gm7) via a iiø7-V7-i progression (Am7b5-D7#9-Gm7).
- Incorporation of the secondary dominant V7/V (C7) leading to the dominant of Bb, followed by a ii-V-I.
Improvisation Focus: Bb Major scale and its diatonic modes (Ionian, Dorian, Mixolydian) and associated arpeggios.
Difficulty Rating: 3 (Intermediate). The tune combines standard ii-V-I movements with clear relative minor tonicization and secondary dominants, requiring an understanding of diatonic harmony and common jazz progressions.
