Harmonic Highlights:
- Establishes the Eb minor key center with the minor i-V progression (Ebm7-Bb7b13).
- Features frequent, distinct modulations, including a prominent ii-V-I-IV progression in Db major (Ebm7-Ab7-Dbmaj7-Gb7).
- Employs sequential ii-V-I patterns in new tonal centers, such as Cm7b5-F7b9-Bbm7 in Bb minor.
- The bridge section presents significant harmonic complexity, shifting to D major (Dmaj7, Em7) before a ii-V in F major (Gm7-C7).
Improvisation Focus: Fluid application of melodic minor and altered scales across frequently modulating ii-V-I progressions.
Difficulty Rating: 4 (Advanced) because of the rapid, distant modulations and numerous altered dominant chords, requiring sophisticated ear training and scale mastery.
