Harmonic Highlights
- Features prevalent II-V-I progressions (Cm7-F7-Bbmaj7) anchoring the piece in Bb major.
- Employs extended dominant cycles (e.g., D7-G7-C7-F7) that propel harmonic movement and build tension towards the tonic.
- Incorporates strategic tritone substitutions (Bb7-Eb7, Ab7) introducing characteristic bebop chromaticism and unexpected resolutions.
- Utilizes secondary dominants (G7 to Cm7, D7 to G7) creating localized tonal centers within the progression.
Improvisation Focus Navigating altered dominant scales and arpeggios over the numerous V7 chords.
Difficulty Rating 5 (Advanced) - Rapid harmonic rhythm, complex dominant cycles, and numerous altered chords demand sophisticated melodic and harmonic understanding.
