Harmonic Highlights
- The initial prolonged C7 establishes a dominant-tonic sound, hinting at blues inflections within a major key.
- Frequent secondary dominants like A7 (V7/ii) directly set up Dm7, driving harmonic motion.
- A classic bebop iii-VI-ii-V progression (Em7-A7-Dm7-G7) provides a quintessential turnaround.
- Standard ii-V-I movements (Dm7-G7-C) firmly establish and reinforce the C major tonality.
Improvisation Focus Precise arpeggio outlining of each chord change.
