Harmonic Highlights:

  • The piece frequently employs extended tonic (G6) prolongation, establishing the key center clearly before moving.
  • Straightforward and repeated ii-V-I progressions (Am7-D7-G6) are highly diatonic, reinforcing G major.
  • The consistent use of G6 as the tonic chord, rather than Gmaj7, provides a classic swing-era or simpler pop-jazz feel.
  • Harmony predominantly remains diatonic within G major, with clear IV-I (Cmaj7-Gmaj7) movements.

Improvisation Focus: G Major Scale

Difficulty Rating: 1 (Beginner). Straightforward diatonic harmony with repeated, predictable progressions makes it highly accessible for developing improvisers.
