Zwilich understands the bassoon. Or rather, she understands the bassoonist’s way of life. “I not only don’t know how you play the bassoon, I don’t know why. You get up in the morning, you have to put this thing together. It’s got wood, which is very temperamental. It’s got cork, which is maybe even more temperamental. You’ve got to make the reed. It’s got all kinds of issues.” Painfully accurate.
