My first arrangement for music box is a theme from the Harry Potter Septet. Being a mathematician, I twisted the paper into a Möbius strip and made this educational video to demonstrate.

Theme begins. The paper is in a loop with a half twist.

A mobius strip is a loop with a half-twist. It has only one side!

This means we can play both sides of the original strip in one pass through the box.

We've gone around the loop. Back to the start of the theme!

But because of the twist, the paper is upside- down. The theme plays inverted.

Now back to the beginning, but the melody is right-side up again.
