Harmonic Highlights:

  • Establishes the F major tonic with a clear I-vi-ii-V-I progression.
  • Features frequent secondary dominants, notably D7 and D7b9, to tonicize the ii minor chord (Gm7).
  • Includes a prominent ii-V-I progression (Cm7-F7-Bbmaj7) leading to a strong tonicization of the subdominant key (Bb major).

Improvisation Focus: Mixolydian scale application over the numerous dominant seventh chords.

Difficulty Rating: 3 (Intermediate). The tune combines standard functional harmony with secondary dominants and a distinct subdominant tonicization, requiring a solid grasp of these concepts.
