  • The recurring G7, C7, F7 sequence features a dominant cycle of fifths (V7/ii, V7/V, V7/I) driving towards the Bb tonic.
  • The Bb7, Eb6 movement provides a characteristic I7-IV blues-inflected progression, common in bridge or subdominant sections.
  • Prolonged C7, F7 pairs serve as a strong V7/V - V7/I dominant preparation, reinforcing the return to Bb major.

Improvisation Focus: Mixolydian scale

Difficulty Rating: 3 (Intermediate). The frequent dominant chord changes and blues inflections require precise navigation beyond basic diatonic playing.
