  • The opening I-VI7(b13)-ii-V progression features an altered secondary dominant (D7b13), creating immediate harmonic interest.
  • A prominent ii-V-I progression (Bm7b5-E7b9-Am7) provides a temporary tonicization of the mediant (Am7).
  • Extended cycles of dominant 7th chords (D7-G7-C7) dynamically lead towards the tonic’s dominant.

Improvisation Focus: Altered Dominant Scales.

Difficulty Rating: 4 (Advanced Intermediate). Its frequent use of altered dominant chords and temporary modulations requires sophisticated harmonic understanding.
