- Features an extended cycle of fifths progression (e.g., D7-G7-C7-F6) creating strong harmonic momentum and temporary tonicizations.
- Employs frequent secondary dominants (e.g., E7-A7) to drive the progression and introduce chromaticism, often functioning as V/V-V in D minor.
- Incorporates a sophisticated turnaround using an altered dominant (A7/C#) leading into a vi-ii-V progression (Bm7-E7-A7), demonstrating advanced harmonic substitution and voice leading.
Improvisation Focus: Chord tone outlining over dominant cycles.
Difficulty Rating: 4 (Advanced Intermediate) - The rapid and extensive dominant cycles, including secondary dominants and altered qualities, demand a sophisticated understanding of harmonic function and efficient voice leading.
