Harmonic Highlights:
- Prominent use of the IVmaj7 - ivm6 - bVII7 - Imaj7 progression, featuring the characteristic minor iv (Ebm6) and borrowed bVII7 (Ab7) resolving to Bbmaj7.
- A classic secondary dominant chain (Dm7-G7-C7-F7) functions as an extended approach to the tonic’s dominant (F7).
- Frequent deployment of dominant 7th chords as primary drivers for harmonic tension and resolution throughout the form.
Improvisation Focus: Mixolydian scales, particularly over the numerous dominant 7th chords and their respective resolutions.
Difficulty Rating: 3 (Intermediate) - The tune features standard jazz harmony with several ii-V-I progressions and secondary dominant chains requiring solid chord-scale understanding.
