Harmonic Highlights

  • Employs an ascending I-ii-iii sequence followed by a VI7 secondary dominant (E7) to pivot back to the ii chord (Am7).
  • Features a modulation to the subdominant (IV) key via a ii-V-I progression (Dm7 - G7 - Cmaj7), shifting the tonal center briefly to C major.
  • Incorporates a minor ii-V-i (C#m7b5 - F#7b9 - Bm7) to reach the mediant, adding sophisticated chromaticism to the diatonic G major landscape.

Improvisation Focus Targeting chord tones (specifically the 3rds and 7ths) to navigate the frequent secondary dominants and the temporary shift to the subdominant key.

Difficulty Rating 3/5: The tune remains largely diatonic but demands fluid navigation of secondary dominants and a minor ii-V transition.
