Steps 1-9 of the Loop Exercise Method
  1. Troubleshoot; find a small fragment that needs work.
  2. Make a loop of the small fragment.
  3. Practice the loop for memorization and continuity.
  4. Settle on a slow speed.
  5. Practice the loop for perfection: clarity/smoothness.
  6. Zero in on anything causing a problem.
  7. Create a smaller loop featuring that flaw, smooth it out.
  8. Lock in the correct way to play smaller loop, then raise speed slowly, keeping it perfect.
  9. When problem section is better, try it in larger loop, keeping it perfect; raise speed.
