- Frequent oscillation between the tonic minor (implied Bb minor) and its relative major, Dbmaj7 (bIII), often established via ii-V progressions like Ebm7-Ab7.
- Incorporation of secondary dominant functions and tritone substitutions, exemplified by Gm7b5-C7b9 (targeting F minor) and the chromatic Gb7#11.
- Distinct modulation to the parallel major (Bb major) via the Cm7-F7 (ii-V) sequence, adding bright contrast and further harmonic complexity.
Improvisation Focus: Chord tone outlining over the rapidly shifting tonal centers.
Difficulty Rating: 4 (Advanced Intermediate) - The frequent modulations, chromaticism, and advanced harmonic devices demand a high level of theoretical understanding and ear training.
