From the teacher:

: I got in a tiff with a violinist in class*
: slapped that girl down hard
: she came in, played like a pig,
: so I suggested that she attempt what beethoven put on the page
: and she got all huffy, played it flat and dead,
: then shouted “It’s boring!”
: and I said, “you’re boring.”
: “no one is paying to hear you*, they’re paying to hear Beethoven, and what you’re playing isn’t Beethoven.”
