How to practice

  1. 1 Count the original barline all the way through, even when the new pulse starts to feel stronger.
  2. 2 Clap or sing the new pulse before improvising so the modulation feels physical, not theoretical.
  3. 3 Drums are muted by default here so the piano and bass make the pulse relationship easier to hear.

Suggested scales & modes

  • F blues scale
  • F minor pentatonic
