In this instructable I will show you how to make a bracelet, that can be played by a music box. Are you looking for a personal gift or a fun activity with kids, than you've come to the right place.

I usually don't wear jewellery, except for bracelets and a few pieces that I've gotten from Mrballeng (because let's face it, his stuff is amazing). So after thinking back and forth on how to make bracelets more interesting I came up with this idea.

So get a "Make Your Own Music Box Kit" and let's get started. I've collected a few different ways how to make the bracelet, in order for you to decide which one you like best.

Thanks a lot to Alex (ahahn-1) for helping me out with the musical theory!

Step 1: How to transpose a song

The music box I use has 15 notes, so it can play 2 octaves. You can of course use a bigger one, but remember that you bracelet will become a lot wider. Your box might come with instructions, mine didn't so I figured I give you a quick explanation on how to use it.

Since the music box does not play any sharps or flats (it plays only the white notes on the piano) you will most likely have to transpose (change the key of) the musical piece you would like to use it with. To modulate a song to a different key the circle of fifths (wikipedia) is a great help. If you take a look at the first picture, you can see that in our case we will have to use either C major, or A Minor, since those are the two keys without any half tone.

If you know how to do it, than you can transpose the song yourself. Luckily for everybody else, there are a number of programs out there that can do this for you.
I've used forte 4 free, which you can download here. If the "Element Pallet" is not shown click on the small icon I have marked in the second picture, to make it visible. Simply add the notes of the piece you would like to play.

So let's assume, that you have one , taking a look at the circle of fifth tells you, that you are dealing with F mayor or D minor. It is a perfect fourth (wikipedia) from F to C. Meaning, that it is encompassing a musical interval of four staff positions or five half tones. So in order to transpose it, you will either have to go four staff positions down or a perfect fifth up. In forte 4 free this can be done by clicking on "Actions" and then either on "Transpose by Interval" or "Transpose by Key".
