You can use your keyboard or your mouse for this project. (I recommend using your mouse) Keyboard controls: C, D, E, F, G, A, B, 0, 1, 2, 3, 4, 5 Letters for matching notes. C for lower C note. 0 for higher C note. Numbers for sharp notes starting with 1 for C# to 5 for A#.
I'm sorry if the notes are wrong. I coded all the sounds in a completely different way than I'm used to, and not to mention I've never played piano, so I couldn't tell if the notes sounded right. This was basically just a long trial and error, but I hope it turned out well.
