Harmonic Highlights:

  • Features a series of rapid tonicizations, frequently using ii-V-I progressions to establish new key centers such as Ab major, C major, and G major.
  • Incorporates sudden, non-diatonic shifts, exemplified by the progression from Dbmaj7 to G7 (V/C) leading to Cmaj7.
  • The recurring Gmaj7#11 highlights the use of the Lydian mode, adding brighter, more expansive harmonic textures.

Improvisation Focus: Voice leading through rapidly changing harmonies.

Difficulty Rating: 5 (Advanced). The rapid and often distant modulations, coupled with frequent key center changes, demand advanced harmonic understanding and agility.
