Harmonic Highlights

  • The progression utilizes a IV7 (C7) leading into a iii-VI-ii-V sequence, adding a bluesy, non-diatonic tension that resolves to Bm7.
  • Modal interchange appears via the ii-V of bIII (Cm7-F7), functioning as a subdominant minor substitute that creates a chromatic path back to the tonic.
  • Frequent secondary dominants (E7, A7, B7) drive the harmony through a cycle of fourths, emphasizing forward rhythmic and melodic motion.
  • The structure toggles between the tonic G major and the relative minor (E minor) using standard F#m7b5-B7 minor ii-V-i cadences.

Improvisation Focus Navigating major and minor ii-V-I sequences using G Major and E Melodic Minor scales.

Difficulty Rating 2/5. The piece is highly functional and follows predictable circle-of-fifths logic, making it an accessible entry point for learning standard jazz vocabulary.
