Harmonic Highlights

  • Employs a foundational I-vi-ii-V cycle in G major, providing the quintessential swing-era rhythmic and harmonic drive.
  • Incorporates a chromatic line clichĂ© in the bridge (Em – Em/D# – Em/D – A7/C#), creating smooth internal voice-leading toward the secondary dominant.
  • Utilizes A7 as a V/V secondary dominant to increase harmonic tension before resolving to the primary dominant, D7.

Improvisation Focus G Major scale and chord-tone targeting, specifically focusing on the 3rd and 7th “guide tones” during ii-V-I transitions.

Difficulty Rating 2/5: The predictable diatonic structure and standard turnarounds make it an accessible entry point for learning swing-style improvisation.
