  • Employs altered dominants (e.g., Ab7#5, Ab9#5) to enhance tension and drive the harmony.
  • Features an extended cycle of dominant 7ths (C9-F9-Bb9-Eb9-Ab7#5) that strongly resolves to the primary V chord.

Improvisation Focus Altered scale application over dominant chords.

Difficulty Rating 4. Requires adept navigation of rapid dominant chord changes and application of altered scales over extended dominant cycles.
