Harmonic Highlights:
- The recurring Cmaj7 - F7 - Bb7#11 progression features a non-diatonic IV7 (F7) preceding a backdoor dominant (Bb7#11) resolving to the tonic.
- A prominent descending chromatic dominant chain (A7#11, Ab7#11, G7#11) builds significant tension towards the tonic C7.
- Widespread use of #11 extensions on dominant chords (Bb7, A7, Ab7, G7) emphasizes the Lydian Dominant sound, contributing to the piece’s angular harmonic character.
Improvisation Focus: Lydian Dominant scale.
Difficulty Rating: 5 (Advanced) – The non-diatonic progressions, complex voice leading, and frequent altered dominants require sophisticated harmonic navigation.
