Harmonic Highlights:
- The opening progression features a striking chromatic descent of altered dominant chords (D7#5#9, G7b5#9, C7b9) creating intense tension before resolution to the tonic F minor.
- Employs extended descending dominant cycles (e.g., F7-Bb7-Eb7-Ab7-Dbmaj7) that facilitate temporary modulations and maintain strong forward harmonic momentum.
- Frequent application of highly altered dominant 7th chords (e.g., C7b9, C7b13) demands precise scale choices beyond simple diatonic or mixolydian approaches.
- The use of secondary dominants and chromatic alterations often obscures direct functional harmony, adding to the harmonic density.
Improvisation Focus: Navigating altered dominant scales and their precise tension resolutions.
Difficulty Rating: 4 (Advanced Intermediate). The rapid harmonic rhythm, frequent modulations, and dense use of complex altered dominant chords demand a sophisticated understanding of jazz harmony.
