Jerry arises from under one of the keys. Tom plays tremolo on this key, hammering Jerry's head with it, and then unsuccessfully tries to smash the mouse beneath the keys. When Tom lifts his fingers, the piano continues playing by itself, with Jerry manipulating the felts from inside. To quiet him, Tom whacks Jerry with a tuning tool. In retaliation, Jerry slams the piano keyboard lid onto Tom's fingers and then pops out on the far right of the piano to attempt to cut Tom's finger with a pair of scissors as he plays a very high note. After six misses, Jerry substitutes a mousetrap for the white keys just below it. Tom plays the keys on either side for a few seconds, but eventually his finger gets caught in the trap.
