First, use the item that you put your right (or left) hand on and move the arrow that is made of tiny pixels to the chopstick with a blanket attached to it. Then, click the left button. Wait for a millisecond for the project to start, then click one of the noted letters on your keyboard to play music. Or you could just press a letter on you keyboard. To stop music, press Space. When you press E, you might have to wait a bit.
Music belongs to owners. I will allow anyone to take this music for their own projects. I don't demand credit, but I would like it.
