Harmonic Highlights:
- Frequent and abrupt modulations to remote key centers, exemplified by the shift from G major to Gb minor (Db7b13 to Gbm7).
- Extensive use of altered dominants (Db7b13, Ab7b9) and Lydian dominant chords (C7#11, Gb7#11) for color and tension.
- Sophisticated ii-V-I progressions establishing new tonalities, like the Ebm7b5-Ab7b9-Dbmaj7 sequence.
- The closing Gb7#11 chord functions as a bII7#11 or tritone substitution, creating a highly chromatic and open-ended resolution.
Improvisation Focus: Chord-scale theory, emphasizing Altered and Lydian Dominant sonorities.
Difficulty Rating: 5 (Advanced). The complex harmonic rhythm and frequent modulations to distant keys demand highly developed harmonic awareness and fingerboard knowledge.
