Harmonic Highlights:

  • The A section relies on a classic diatonic I-VI-II-V progression in C major (Cmaj7, Am7, Dm7, G7).
  • The bridge features a clear tonicization of A minor via a ii-V-I progression (Bm7b5-E7b9-Am).
  • This is followed by another ii-V-I to E minor (F#m7b5-B7b9-Em7), creating a sequential chain of minor key resolutions.
  • Frequent use of altered dominants (E7b9, B7b9, A7b9) adds color and tension-resolution opportunities.

Improvisation Focus: Arpeggios outlining chord changes and voice leading through sequential ii-V-I progressions.

Difficulty Rating: 3 (Intermediate). While the A section is diatonic, the bridge features sequential ii-V-I progressions to minor keys and altered dominants, requiring specific harmonic understanding beyond basic major scales.
