Firstly, the notes are a,b,c,d,e and f. And in order to play those notes, press the a key for note A, press the b key for note B, the c key for C note and etc. Press the up arrow for higher pitch and down arrow for lower pitch. Right arrow for higher volume and left arrow for lower volume.
I got inspired by a scratch tutorial. It took me about 20 minute. What songs can you play? Comment below
