Harmonic Highlights

  • The progression utilizes a prolonged IV-iii-VI-II-V-I cycle, creating a strong sense of forward momentum through the circle of fifths.
  • The composition begins on the subdominant C6 (IV), delaying tonic arrival to generate a distinctive sense of melodic suspension and harmonic “softness.”
  • Secondary dominants, specifically E7 (VI7) and A7 (II7), are employed to tonicize the upcoming ii-V-I cadences, enriched by altered extensions like G7b9 and E7#5.
  • The Eb°7 functions as a #ii° chromatic passing chord, providing a smooth voice-leading bridge back to the G/D (I) during the turnaround.

Improvisation Focus G Major Bebop scale and targeting the 3rds and 7ths of the secondary dominants (E7, A7, D7).

Difficulty Rating 2/5 — The harmonic path follows a logical, diatonic-based cycle of fifths that is predictable for intermediate improvisers.
