Drag notes to staff, then press the green play button. You can pause the playback or stop it and start over. The red X clears out all your notes. Remember, only four beats per measure. The line with the two dots next to it means repeat, so the whole one will play twice. YOU CAN CHANGE THE INSTRUMENT WITH THE SLIDER!!! sorry, I remixed this before the original maker updated it.
NEW: -you can change instrument with slider -treble clef and time signature -repeat sign -measures -only 4 beats per measure -new background -volume slider
