Click the notes on the piano, but it only makes a sound if it is on the sheet,, if the sheet said D, then you have to press the D note. It may take a bit of time for it to move onto the next note because that particular sound hasn't finished yet. There was nothing I could do about that though, sorry. :( It may also seem like it is repeating the same note, but it isn't. I hope you enjoy it!
Moss-Shadow made the piano, not me. I tried to make a piano, but it did not work. T_T
