Me and my piana

This is fun, I hit the keys and a whole symphony of electric stuff bursts out.
Until someone changes the setting then the noise only comes out a note at a time. My Dad likes to use the 'whole symphony' version to make it look like he can play properly.
He can't.
But my mum can play twinkle twinkle little star even with the thing upside down, which is pretty impressive even if twinkle twinkle is the only tune that fits into five notes.
Rachmaninov or bust.
