I have a pretty good idea what the wife might say to me hitting the dining table with drum sticks!!!
I was wondering if it might work on the top surface of a keyboard instrument. . .
But the correct technique is to offer it as the lesser of two evils. . . .
You will allow me to clip one small ‘sensor’ on the table or I will buy a old motorbike and strip it on the table . . .
You will only get the occasional complaint about the wire . . .
