Harmonic Highlights:
- The G#07 functions as a chromatic passing diminished chord, creating tension before resolving towards the IV chord (F/A).
- A prominent tritone substitution is used with Db7/Ab (bII7), which then deceptively leads into a ii-V progression (Gm7-C7) in the key of F.
- The Ab7/Eb (bVI7) introduces a characteristic backdoor dominant sound, implying potential resolutions to distant tonal centers or a bluesy inflection.
Improvisation Focus: Navigating altered dominant and tritone substitution chords effectively.
Difficulty Rating: 4 (Advanced Intermediate). It combines standard diatonic harmony with sophisticated chromatic substitutions and temporary modulations, demanding precise harmonic awareness.
