Harmonic Highlights:
- Establishes a clear G major tonality primarily through strong I-V7-I movements.
- The
Abdim7functions as a chromatic passing diminished chord, creating a brief tension before resolving to theAm7(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.
