Harmonic Highlights

  • Utilizes a standard I-vi-ii-V turnaround (C6-Am7-Dm7-G7) and III-VI-II-V extensions, functioning as a “Rhythm Changes” derivative in C major.
  • Features a chromatic ascending transition (F - F#dim7 - C/G), providing a gospel-tinged resolution that strengthens the return to the tonic.
  • Employs static diminished 7th (C°7) blocks as rhythmic hooks, creating symmetrical tension common in swing-era “riff” tunes.

Improvisation Focus C Major Pentatonic and Blues scale integration over diatonic turnarounds.

Difficulty Rating 2/5: The predictable AABA structure and diatonic harmony are accessible, though the piece is often performed at high tempos requiring significant rhythmic precision.
