Harmonic Highlights:

  • The “A” sections predominantly feature the classic I-vi-ii-V progression in Bb major (Bb6-Gm7-Cm7-F7).
  • The “B” section (bridge) is characterized by a cyclical sequence of dominant seventh chords (D7-G7-C7-F7), functioning as V7/vi, V7/ii, V7/V.
  • Incorporates diatonic extensions and common secondary dominant functions to enrich the harmony.

Improvisation Focus: Mixolydian scales applied accurately over the rapidly changing dominant seventh chords in the bridge.

Difficulty Rating: 3 (Intermediate). The “A” sections are straightforward, but the bridge’s fast-moving dominant cycle demands precise chord-scale navigation.
