MELISSA BLOCK, HOST:
We wrap up this hour with a bit of musical Trade Lingo. We've been asking about words that are terms of the trade in a particular line of work - words that might stump anybody else. And today, our trade lingo is offered up by musician and producer Don Was. It's a word musicians use when they screw up.
DON WAS: If you play a mistake it's called a clam.
BLOCK: Why is it called a clam?
WAS: That's a good one. I don't know. (Laughter) I should know. It's probably rooted in something unsavory. I'm trying to think what the origin could be. You know, they're just sort of, like, floppy (Laughter) you know, like a clam.
BLOCK: So clams are wrong notes - something audibly wrong that makes you wince and maybe enrages a bandleader. Clams come up again and again in a legendary tirade by the jazz drummer Buddy Rich excoriating his band. Rich was recorded secretly on his tour bus in the early 1980s by his pianist Lee Musiker.

BUDDY RICH: Look, I'm trying to play. What do you play - clams? You guys know where the [bleep] next set goes. If I hear one [bleep] clam from anybody, you've had it. One clam and this whole [bleep] band is through - tonight. Try me.
BLOCK: That's drummer Buddy Rich reeling about the clam. Now we're told that clam can be used as a noun or verb. Oh, that was a horrendous clam. Or let's do that again, I clammed a note. If there are any musicians out there with ideas of why it's called the clam, please let us know. We're on Facebook and Twitter - @npratc. Transcript provided by NPR, Copyright NPR.
