Harmonic Highlights
- Rapid ii-V sequences (Em7-A7 to Fm7-Bb7) create harmonic tension by delaying resolution to the temporary tonic Ebmaj7.
- Frequent whole-step and half-step modulations force the harmony through transient key centers including D, Eb, and Db.
- Use of chromatic “side-slipping” and dominant substitutions (e.g., Cm7 to B7) facilitates voice leading between distantly related tonal centers.
Improvisation Focus Target-note navigation through rapid ii-V cells.
Difficulty Rating 5 (Advanced): The relentless pace of non-diatonic key changes and the lack of a stable tonic center demand expert-level harmonic fluency and technical precision.
