Harmonic Highlights:
- Features a rapid succession of ii-V-I progressions (Cm7-F7-Bb6) and their variants (Dm7-G7-Cm7-F7), establishing a strong tonal center in Bb.
- The Bb7/D - Eb6 - E07 movement introduces a V7/IV chord followed by a chromatic diminished (E07), characteristic of ‘Rhythm Changes’ bridge harmony, creating tension towards the tonic or dominant.
- A prominent D7-G7-C7 sequence employs a descending cycle of secondary dominant 7th chords, driving harmonic momentum and demanding agile changes.
Improvisation Focus: Navigating ii-V-I progressions with an emphasis on chord tones and dominant scale applications (e.g., Mixolydian).
Difficulty Rating: 4 (Advanced-Intermediate) due to its fast tempo, quick harmonic rhythm, and frequent use of secondary dominants and diminished chords.
