Harmonic Highlights:

  • Prominent use of the V7#5 (C7#5) for altered dominant tension, immediately resolving to the Fmaj7 tonic.
  • Incorporates a ii-V-I progression (Cm7 - F7 - Bbmaj7) that temporarily tonicizes the subdominant (Bb major).
  • Features a chromatic dominant movement with Bb7 leading to A7 (V/vi), followed by a Dm7 - G7 cycle, creating intricate secondary dominant tension.

Improvisation Focus: The Melodic Minor Scale.

Difficulty Rating: 4 (Intermediate-Advanced). The frequent use of altered and secondary dominants, alongside swift harmonic rhythm, demands advanced harmonic comprehension and improvisational agility.
