Have some fun pretending you're a piano virtuoso using machine learning!
Use the 1-8 numbered keys on your keyboard (or the home row a-f and j-;) or touch the coloured blocks to play the piano. Use the space bar to control the sustain pedal. The more you pretend you're a real player, the better the melody (and you!) will sound.
