- The piece frequently tonicizes the subdominant (Ab major) through sequential ii-V-I progressions, as seen with
Cm7-Fm7-Bbm7-Eb7-Abmaj7. - A notable modulation occurs to C major (
Dm7-G7-Cmaj7), approached via descending ii-V relationships, creating a temporary new tonal center. - A significant chromatic shift to E major (
F#m7-B7-Emaj7) introduces a distant key change, requiring rapid harmonic adaptation.
Improvisation Focus: Navigating rapid modulations by targeting chord tones and understanding the temporary tonic.
Difficulty Rating: 4 (Advanced Intermediate). The frequent and often distant modulations demand a strong command of chord-scale theory and rapid harmonic recognition.
