No obvious ii-V patterns detected.


  • The tonic F7 functions as a minor blues I7 chord, setting a bluesy, dominant-tonic foundation.
  • An extended cycle of dominant 7ths (Bb7, Eb7, Ab7, Db7) creates rapid, successive V7-I progressions (implied) moving down a cycle of fourths.
  • The B7 to Bb7 movement introduces a chromatic dominant descent, adding unexpected tension and color outside a conventional cycle.
  • Frequent C7 appearances firmly re-establish F as the tonic center, despite the preceding complex dominant harmony.

Improvisation Focus: Arpeggio outlining of dominant 7th chords and their corresponding scales (Mixolydian, Altered) to clearly articulate the rapid harmonic shifts.

Difficulty Rating: 5 (Advanced). Requires a sophisticated harmonic vocabulary to navigate the fast-moving dominant cycles and chromatic alterations within a blues framework.
