Harmonic Highlights
- Prominent application of secondary dominants (A7 as V7/ii, D7 as V7/V) drives strong harmonic motion towards the tonic C.
- A temporary tonicization of the subdominant (IV) is achieved with the C7 leading to F, a common blues-infused jazz progression.
- The recurring A7-D7-G7 sequence forms a classic jazz turnaround, utilizing a dominant cycle that effectively leads back to the tonic.
Improvisation Focus Mixolydian scales over each dominant chord.
