Harmonic Highlights:

  • Extended cycle of 5ths progression (Gm7-C7-F7-Bb7-Ebmaj7) provides strong forward momentum towards the tonic.
  • Chromatic alterations and tritone substitutions are prevalent, notably the Db7 after Abmaj7, creating harmonic tension.
  • Temporary modulations through iiø7-V7 progressions, such as Am7b5-D7b9 resolving to Gm7 (III minor), broaden the harmonic palette.

Improvisation Focus: Chord tone outlining and arpeggio mastery across diverse chord qualities.

Difficulty Rating: 4 (Advanced Intermediate) - Navigating the frequent modulations, extended II-V-I chains, and chromatic alterations requires a solid understanding of jazz harmony.
