Select an instrument by pushing a button. Then make music! To play the note C, push the key S on your keyboard. For D press D, E press F, and so on. There's a chart in the project if you forget. Basically S to L is C to C2. (High C) Have fun! Oh, and of course push the green flag to start!
All coding and sprites by me. The notes are from Scratch! Yeah, I know it doesn't sound great. I made a new version with more instruments and notes! Go check it out here: https://scratch.mit.edu/projects/1133291781/
