Harmonic Highlights:

  • Establishes a clear G major tonality primarily through strong I-V7-I movements.
  • The Abdim7 functions as a chromatic passing diminished chord, creating a brief tension before resolving to the Am7 (ii chord).
  • Extensive dominant prolongation (D7) firmly sets up the return to the tonic, typical of early jazz and ragtime.
  • Relies heavily on diatonic ii-V-I progressions for fundamental harmonic movement.

Improvisation Focus: G Major scale.

Difficulty Rating: 1 (Beginner) - The harmonic progression is largely diatonic and straightforward, making it highly accessible for new improvisers.
