- The opening features a deceptive resolution from Eb7 (I7) to D7#9 (V7/Gm), resolving chromatically to Gm7 (iii).
- A striking chromatic mediant shift occurs with Abmaj7 (IVmaj7) abruptly moving to Bmaj7 (bVImaj7).
- A complex dominant progression includes C7 (V7/F), a tritone substitution to Gb7, followed by F7 and Bb7, creating a rich series of altered dominant functions.
Improvisation Focus: Altered Dominant scales and chromaticism.
Difficulty Rating: 5 (Advanced) The rapid, non-diatonic chord changes, frequent use of altered dominants, and complex modulations demand a sophisticated understanding of advanced jazz harmony.
