Each key is wired to a taser. Enter the song you're going to try to play. The smart piano now knows what key should be hit and when. Hit the wrong key you get zapped. Hit two wrong keys at the same time? Ooo, you REALLY don't want to do that. Playing a classical piece with 5 fingers on each hand? Might want to practice a bit before turning on the juice.

You can of course adjust the tolerance level of the timing, but you can't hit any wrong notes. Ever.

The voltage likewise can be adjusted.

Want to be the center of attention at a party by playing piano? This will really assist in you achieving your dream.

"In 4' 33", no-one can hear you scream ..."

Could there be a bagpipes version of this, with a stick of PETN in the chanter ?

There are no wrong notes. Only interesting new improvisations.
