Harmonic Highlights

  • Relies heavily on diatonic II-V-I progressions, establishing a strong foundation in F major.
  • Features a clear, temporary modulation to Ab major, introduced by a Bbm7-Eb7-Abmaj7 II-V-I sequence.
  • Incorporates secondary dominants, such as D7 (V/ii), to extend harmonic movement within turnaround figures.
  • The Bb7 chord functions as a V7/IV, briefly coloring the subdominant before resolving to the tonic.

Improvisation Focus Navigating II-V-I progressions across changing key centers (F major and Ab major).

Difficulty Rating 3 (Intermediate) - Requires familiarity with standard II-V-I changes and confident execution through a common, functional modulation to Ab major.
