- The progression utilizes a chromatic ascending line cliché on the tonic (Bb - Bbaug - Bb6 - B°7), creating a smooth melodic transition to the ii chord (Cm).
- Minor line clichés are prominent, specifically on the ii chord (Cm - Cmb6 - Cm6) and the vi chord (Gm - Gm/Gb), necessitating focus on shifting 5ths and 6ths.
- Frequent use of secondary dominants (G7 to Cm, D7 to Gm) and a functional ii-V-I structure into the subdominant (Fm7 - Bb7 - Eb) provides a classic, cyclical harmonic flow.
Improvisation Focus Voice leading through chromatic line clichés and melodic minor substitutions.
Difficulty Rating 3/5; while the key center remains stable, the performer must navigate constant internal chromatic movement and precise voice leading.
