Find Lead Sheet on Sheet Music Direct (PDF)Harmonic Highlights
- Rapid sequential ii-V progressions modulating through distant key centers including Bb, A, and Db major.
- Utilization of minor ii-V (Am7b5-D7b9) to establish a Gm tonality before shifting abruptly to major-key resolutions.
- Strategic use of non-functional chromaticism and tritone substitutions (B7#11 to Bbmaj7) to connect disparate tonal centers.
Improvisation Focus Continuous modulation navigation using guide tones to bridge shifting ii-V-I cells.
Difficulty Rating 4/5; the rapid-fire modulations every two beats demand advanced harmonic fluency and the ability to transpose melodic ideas instantly.
