Here’s an excerpt:
Casady: You have to remind them that it is a workshop. In the very first session of a weekend, I run a song through to see who’s doing what, how quick they are. What’s their left-hand technique, right-hand technique – and whether they’re getting decent tone? Do they hear the music and assimilate it and get around the instrument well? Or are they just completely lost? I then match up jobs I give with their abilities.
