Pressing <Shift> anytime clears your notes, so you can start over again (after the tune plays).
There is a (small)
bug in the code that when you press <Shift> while the tune is already playing, the extra notes get recorded as your own. To clear them and start over, wait until the tune is finished and press <Shift> one more time...After the tune has finished playing, you are good to go again.
