I feel like I learned nothing yesterday!  Need more work on percussion.

Still trying to record Prelude 1. It's hard to get any useful takes because my hands cramp up playing it after one time through.

Working on Prelude 3 and trying to coordinate soundboard taps. I'm definitely not a percussionist and they're easier to play faster.

Measured some string lengths, but had to stop because I was bending and craning my neck repeatedly.  String lengths may vary by up to 1/8" because I don't have sn accurate tool to measure them. What would you use?
