My quest for easier pieces that I can play perfectly isn't going so well. Here's the next one from the Louchez book, #2. It's long and sustained (titled Sonority), and I found it hard; it took me quite awhile to get through it without falling apart. I think it'd sound better with vibrato, but I stopped trying to add any, because it screwed me up. So all the oscillation remaining is the stuff I can't control. Ah well, I guess it makes me sound human.
