Harmonic Highlights

  • The progression utilizes a foundational I-vi-ii-V (Gmaj7-Em7-Am7-D7), establishing a clear diatonic framework typical of Hoagy Carmichael’s melodic style.
  • A iii-VI7b9 sequence (Bm7-E7b9) serves as a secondary dominant turnaround, introducing harmonic tension that resolves smoothly to the ii-V.
  • The inclusion of a secondary ii-V (Dm7-G7) tonicizes the subdominant (Cmaj7), creating a brief but effective shift in tonal center.
  • Modal interchange is used via the Cmaj7 to Cm/maj7 movement, providing a sophisticated “minor-major” color through the chromatic descent of the 6th scale degree.

Improvisation Focus G Major Bebop scale, with specific focus on targeting the Eb natural over the Cm/maj7 chord.

Difficulty Rating 2: The piece follows predictable functional harmony and standard jazz turnarounds, making it an ideal study for intermediate-beginner improvisers.
