Harmonic Highlights

  • Frequent use of cyclic ii-V-I progressions (Am7-D7-Gmaj7) establishes a strong diatonic foundation in G major.
  • Incorporation of secondary dominants (E7 to Am7 and A7 to D7) creates chromatic momentum through the circle of fifths.
  • The B7b13 to Em7 (V/vi to vi) movement provides a brief, effective pivot into the relative minor, adding harmonic depth.
  • Subdominant color via the IV7 (C7) chord introduces a subtle blues inflection within the primary major tonality.

Improvisation Focus G Major Bebop Scale (utilizing the chromatic passing tone between the 5th and 6th degrees to smoothly navigate the frequent ii-V-I cells).

Difficulty Rating 2/5: The tune primarily utilizes standard diatonic movements and predictable secondary dominants, making it highly accessible for intermediate improvisers.
