Harmonic Highlights:
- The striking chromatic progression from E7alt to Ebmaj7, implying a brief, non-diatonic shift or unexpected resolution.
- An extended cycle of secondary dominants (D7-G7-C7) that resolves unexpectedly to the iv minor (Gm) instead of its expected tonic.
- Sophisticated use of a backdoor ii-V progression (Bm7b5 - Bb7 - Am7) to temporarily tonicize the dominant minor (Am).
- Strategic tritone substitution (Ab07 for D7) before the ii-V-I resolution into the relative major (Gm7-C7b9-Fmaj7).
Improvisation Focus: Altered Dominant Scales
Difficulty Rating: 4 (Advanced Intermediate). Its frequent use of altered dominants, tritone substitutions, extended dominant cycles, and non-standard resolutions requires a flexible harmonic vocabulary.
