QWERTY piano
Your computer keyboard as a piano. The home row plays the white keys; the row above plays the black keys.
Play
Click the pad to arm it, then type. A to L are the white keys from C; W E, T Y U and O P are the black keys between them. R and I stay silent, where E meets F and B meets C with no black key between. Z and X move everything an octave; C and V make the next notes softer or louder. Keys match by position, so non-QWERTY boards work too.
