Harmonic Highlights:
- Features a chromatic diminished chord pair (
G07, Gb07) creating tension and unexpected passing motion. - Includes a clear, temporary modulation to the relative major (
Dbmaj7section viaGbmaj7-Db/F-Ebm7-Dbmaj7). - Frequent V/V-V cycles (
C7b9-F7b9) strongly resolve to the tonic or new temporary key centers. - Incorporates major-mode tonicization (
Cm7-F7leading to Bb major) within the overall Bb minor context, creating harmonic ambiguity.
Improvisation Focus: Navigating rapid harmonic rhythm and targeting chord tones through various temporary key centers.
Difficulty Rating: 5 (Advanced) Rapid harmonic rhythm, complex dominant and diminished chord voicings, and frequent modulations demand a sophisticated understanding of functional harmony and improvisation techniques.
