Harmonic Highlights:
- Features an extended cycle of fifths through various ii-V progressions, frequently targeting temporary minor tonalities (e.g., Bm7b5-E7b9 towards Am7).
- Prominently utilizes altered dominant chords (E7b9, D7b9) to create harmonic tension before resolution.
- Incorporates a classic backdoor dominant progression (Bbm7-Eb7) to resolve smoothly to the Fmaj7 tonic.
- Includes multiple iiø7-V7b9 movements (e.g., Am7b5-D7b9 to Gm7) demanding navigation of minor key harmony.
Improvisation Focus: Navigating altered dominant scales and arpeggios.
Difficulty Rating: 4 (Advanced Intermediate) - The frequent use of altered dominants, iiø7-V7b9 chains, and a backdoor progression requires sophisticated harmonic understanding and improvisational agility.
