I am married to an amateur drummer, a modern jazz drummer, swing-bebop or whatever: not rock. All his musician friends still play together now and again just for the fun of it, they are now all golden oldies, but they can still swing. So these are drumming hands.
and here he is in action. Note that his hands never leave his wrists.
Tabby decided she also wanted to get in on the act. After all she has four hands.
And then she decided to show her special claw.
