🎼 Sheet Music
Find Lead Sheet on Sheet Music Direct (PDF)Harmonic Highlights:
- Utilizes sequential ii-V-I modulations descending by whole steps (G major to F major to Eb major), a hallmark of the “How High the Moon” contrafact.
- Employs a sudden shift to the parallel minor (Gm7-C7) to initiate the modulation away from the tonic Gmaj7.
- Features a minor ii-V-i turnaround (Am7b5-D7b9-Gm7), introducing chromaticism and tension before re-establishing the G major tonal center.
Improvisation Focus: Navigating fluid voice-leading through rapid, descending sequential key changes.
Difficulty Rating: 4/5. The high bebop tempo and frequent shifts into non-diatonic keys (F and Eb) require advanced harmonic mapping and technical facility.
