Harmonic Highlights

  • The progression utilizes a diatonic sequence within Bb Major, specifically cycling through iii (Dm), V (F), I (Bb), and IV (Eb).
  • The structure avoids functional ii-V-I cadences in favor of modal tertian relationships, creating a floating, non-directional harmonic feel.
  • A slow harmonic rhythm of two bars per chord emphasizes melodic development over rapid vertical navigation.
  • The transition from F to Bb acts as a soft V-I resolution, while the Eb provides a Lydian-inflected subdominant release.

Improvisation Focus Bb Major Scale (specifically D Phrygian and Bb Lydian modes).

Difficulty Rating 2/5: The strictly diatonic nature and slow harmonic rhythm make it accessible for beginners, though the avant-garde context requires advanced rhythmic interplay.
