DISCLAIMER. This is a toy. You won't be performing with this piano, but it's fun and a quick demonstration tool. You can only play one key at a time and there's a slight lag but notes will sustain long enough to play an arpeggio. If you have touchscreen or a smartboard, you can play it more easily or let students come up and play with it. Depending on your pointing tool, you might have to shake the mouse to wake up the cursor before students use a stylus on the board. It's good for giving pitches for sight-singing or demonstrating some scales to give a taste of what the music will sound like.
