Harmonic Highlights

  • The progression utilizes persistent I–VI7–ii–V turnarounds, where the secondary dominant VI7 (E7) replaces the diatonic vi to create a bluesier, gospel-inflected pull to the ii chord.
  • Integration of the #IVdim7 (C#°7) provides a chromatic bridge between the subdominant IV and the tonic, typically resolving to the I chord over a dominant pedal (G6/D).
  • Use of the V7#5 (D7#5) in turnarounds provides specific melodic tension and smooth chromatic voice leading (A# to B) back to the tonic Gmaj7.
  1. Improvisation Focus G Major Bebop scale, with a specific emphasis on targeting the 3rd of the VI7 chord (G#) to navigate the chromaticism of the turnaround.

  2. Difficulty Rating 3 (Intermediate) – While the structure is repetitive, the soloist must navigate constant secondary dominants and chromatic diminished passing chords with fluid voice leading.
