Harmonic Highlights

  • The I-IV7 (Gmaj7 to C7) movement introduces a bluesy, subdominant flavor typical of early swing era compositions.
  • Employs a standard iii-VI-ii-V turnaround (Bm7-E7-Am7-D7), utilizing secondary dominants to propel the harmony back toward the tonic.
  • Features a #IV diminished chord (C#o7) for chromatic voice leading, bridging the subdominant (Cmaj7) back to the tonic (Gmaj7).
  • Incorporates a ii-V-i minor cadence (F#m7b5-B7b9-Em7) to provide a brief modulation into the relative minor key of E minor.

Improvisation Focus G Major Blues Scale combined with chord-tone targeting (arpeggios).

Difficulty Rating 2/5; the predictable AABA structure and clear functional cadences make it an ideal entry point for navigating standard jazz turnarounds.
