Press the flag and wait for the music! Give it a while to generate the music. It's a long script and will likely take a while, especially if you choose to show the variables. If it's been over 30 seconds, then check your volume.
Tell me in the comments whether you like it or not (though it will be different every time!). It will always be in C major, but it's simple enough to change that. Again, look at the notes.
