  • The use of C6 and Cmaj7 effectively prolongs the tonic, showcasing nuanced variations of the primary I chord.
  • A chromatic Eb07 chord introduces unique tension, preceding the Dm7 and adding non-diatonic color through an upper neighbor diminished approach.
  • Extended Dm7 chords (four consecutive bars) before G7 emphasize the ii-V progression through duration.
  • The C#07 chord functions as a clear vii°7/ii, strongly leading into the subsequent Dm7-G7 resolution.

Improvisation Focus: Navigating ii-V-I arpeggios and their associated modes (Dorian for ii, Mixolydian for V).

Difficulty Rating: 3 (Intermediate). Its clear ii-V-I progressions are approachable, but the chromatic diminished chords (Eb07, C#07) require careful harmonic navigation.
