Harmonic Highlights:
- Frequent tonicization of the relative major (Fmaj7) via ii-V-I progressions (Gm7-C7).
- Extensive use of secondary dominant chords with altered extensions (G7#11, D7b9, A7b9) to briefly tonicize various key areas.
- Prominent application of tritone substitution (Gbmaj7 often substituting for C7) creating rich chromatic color, resolving to Fmaj7.
- Seamless blend of traditional minor ii-V-i progressions (Am7b5-D7b9 to Gm, Gm7-A7b9 to Dm) with major key harmonic movements.
Improvisation Focus: Chord-scale application, particularly for altered dominant and tritone substitution harmonies.
Difficulty Rating: 4. Its frequent modulations, altered dominants, and tritone substitutions demand precise harmonic navigation and advanced melodic vocabulary.
