Harmonic Highlights:
- Frequent tonicization of the relative minor (Dm) via Em7b5-A7b13-Dm7 progression.
- Prominent ii-V-I in Bb (Cm7-F7-Bbmaj7) effectively tonicizes the subdominant.
- Chromaticism is introduced by Db7 (bII7 of Cm7) and altered dominant chords like A7b13, D7b9, and C7#5.
- Extended ii-V patterns (e.g., Am7b5-D7b9) set up progressions to Gm or create deceptive resolutions.
Improvisation Focus: Navigating local ii-V-I changes and their associated scales/arpeggios.
Difficulty Rating: 4 (Advanced Intermediate). The song features standard ii-V-I movements with moderate chromaticism, altered dominants, and common tonicizations, requiring fluency in navigating local key centers.
