Harmonic Highlights
- A prominent descending cycle of iiø-V7 progressions (e.g., Gm7b5-C7b9, Fm7b5-Bb7b9), often resolving to a new temporary tonic a whole step below.
- Extensive use of V7b9 alterations (C7b9, Bb7b9, Ab7b9), intensifying dominant function and contributing to the bebop sound.
- Strategic movement towards the tonic (Ebm7b5-Ab7b9-Dbmaj7) followed by modulation to the subdominant (Abm7-Db7-Gbmaj7), showcasing both resolution and continued harmonic exploration.
- Unexpected dominant chords like D7 after Am7-Db7, indicating secondary dominants or chromatic substitutions that add harmonic surprise.
Improvisation Focus Navigating rapid ii-V-I progressions with precise application of altered scales and arpeggios.
Difficulty Rating 5 (Advanced). The piece demands agile navigation through numerous altered dominant chords, half-diminished ii chords, and quick modulations at a typically fast tempo.
