A guitarist friend once told me that it’s a point of honour among guitarists not to have too much extraneous noise when they play. “You want to minimize all the bumps and squeaks — anything that’s not music,” he told me.
"Oh yeah, cellists should do that too,” I said.
My friend snorted. “Cellists are the worst,” he said. “They’re always slamming and hitting and grunting and huffing and puffing like they’re the Big Bad Wolf or something.”
