Harmonic Highlights

  • The progression utilizes modal interchange via the bVII (Ab major), momentarily shifting the tonal center from Bb Ionian to Bb Mixolydian.
  • The C/Bb chord functions as a II/I slash chord, introducing a Lydian-inflected color over the tonic pedal before resolving back to Bb.
  • A chromatic descending bassline occurs during the Gm - D7/F# - Gm/F - Ebmaj7 sequence, employing a secondary dominant (V/vi) to create internal tension within the relative minor.
  • The use of F7sus to F7 creates a classic dominant prolongation, delaying resolution to the tonic and emphasizing the track’s anthemic, folk-jazz aesthetic.

Improvisation Focus Bb Major Pentatonic. The composition’s soaring, melodic nature demands a thematic approach that prioritizes chord tones and lyrical phrasing over complex vertical substitutions.

Difficulty Rating 2/5. The harmonic rhythm is predictable and the changes are largely diatonic, making it an excellent study in maintaining melodic integrity over simple modal shifts.
