to play on any instrument (guitar, drums, brass, etc.). Used
for guitar and drums because of the chopping motion
made by the hand, and used
for wind instruments because chops is also slang for one's mouth.
On drums: He played the ditty so fast. . . he has amazing chops.
On guitar: Did you hear that solo? He's got wicked chops!
On brass: You have
some chops to hit a double G.
