- While the key center was stated as A minor, the provided chord sample overwhelmingly establishes C major as the tonic, with Cmaj7 functioning as the I chord and frequent ii-V-I resolutions.
- Secondary dominant chords are prominently featured, such as E7 (V/vi), A7 (V/ii), and D7 (V/V), creating dynamic harmonic propulsion and leading to temporary tonicizations.
- The progression relies heavily on foundational jazz movements like the ii-V-I (Dm7-G7-Cmaj7) and extended dominant chains (D7-G7-Cmaj7).
- The E7-Am7 sequence provides a classic V/vi to vi cadence, introducing a momentary minor-key color within the overall major tonality.
Improvisation Focus: C Major scale and arpeggios, incorporating Mixolydian modes over the numerous dominant 7th chords.
Difficulty Rating: 2 (Beginner-Intermediate). The song’s clear structure and repetitive chord patterns are accessible, but improvising over the secondary dominant chords requires awareness of target tones and appropriate scale choices.
