Harmonic Highlights
- Frequent use of secondary iiø7-V7alt progressions, notably Bm7b5-E7#9 resolving to Am7 (vi), creating strong temporary tonicizations.
- The B7#9 resolving directly to Cm7 (i) functions as a modern bII7 chord (Cb7#9), providing a highly altered and striking dominant cadence to the tonic.
- Non-diatonic root movements and chord qualities, such as the opening Em7, establish a fluid, modal, and open harmonic landscape from the outset.
Improvisation Focus Applying specific scales over each chord, especially Altered or Lydian Dominant over V7alt chords, while maintaining an overall C minor sensibility.
Difficulty Rating 4 (Advanced) - The rapid, non-diatonic modulations and sophisticated altered dominant resolutions require a deep understanding of jazz harmony.
