Harmonic Highlights:

  • Frequent tonicization of the IV chord (F major) and the bVII chord (Bb major), often via ii-V progressions.
  • Extensive use of altered secondary dominants (A7b13, E7b13, Ab7#5) for chromatic interest and tension.
  • Prominent minor ii-V-i progressions (F#m7b5-Bm7b5-E7b13-Am6) leading to the relative minor, A minor, before navigating back to the tonic.

Improvisation Focus: Melodic Minor Scale modes, especially over altered dominant chords and minor ii-V sections.

Difficulty Rating: 5 (Advanced) due to frequent modulations, complex altered dominants, and rapid harmonic rhythm requiring precise chord-scale application.
