- The progression features a recurring I - ivm (Bbmaj7 to Ebm/Bb) modal interchange over a tonic pedal, utilizing the minor plagal cadence for a melancholic quality.
- A structural shift to the relative minor occurs through a standard ii-V-i sequence (Am7b5 - D7#9 - Gm7), anchoring the G minor tonality.
- The sequence Gm7 - C7 - F7 acts as a vi - II7 - V7 turnaround, employing a secondary dominant (C7) to pull strongly back toward the Bb major tonic.
Improvisation Focus Melodic emphasis on the b6 degree (Gb) during the Ebm/Bb chords to highlight the shift from the major to the parallel minor tonality.
Difficulty Rating 2/5 — The slow harmonic rhythm and clear functional modulations provide ample space for soloists, though navigating the minor iv chord requires precise ear training.
