Harmonic Highlights
- Frequent use of iiø-V7-i/I progressions, often quickly shifting temporary tonic centers (e.g., Em7b5-A7b9 to Dm, Dm7b5-G7b9).
- Prominent tritone substitutions (Ab7 for D7, Bb7 for E7) providing colorful, unexpected dominant resolutions.
- Chromatic descending root motion (Bm7-Bbm7-Am7-D7) creating a characteristic jazz voice-leading cliché.
- Extensive application of altered dominants (G7#5, G7b9, A7b9) and borrowed chords, enhancing harmonic tension and movement.
Improvisation Focus Mastery of altered dominant scales and their application over constantly shifting dominant functions.
Difficulty Rating 5 (Advanced) – The tune features numerous rapid modulations, altered dominants, and harmonic substitutions demanding precise scale and arpeggio choices.
