You build a musical box with anything, my app plays the notes while you rotate it.


 



 

Step 1: Build You Box

This part is very flexible. Whatever how your box looks like. If the paper is visible and vertically movable you are good.

example:
- a cardboard for the box
- an empty jar of peanut butter for the rotative cylinder
- a little wood stick for the axis of the cylinder
- an ice cream stick to manually rotate the cylinder
- a piece of paper to write the notes on

other example:
- toilet paper

Step 2: Download My Application

You need a mac OSX 10.6+ and a webcam.
- Download the application here, unzip it, run it.
- Position your musical box in front of your computer, the opened side in front of the webcam.
- Drag the 2 circles on the right and left borders of your music sheet.
- play the musical box - keep its base still or the notes will be wrong.

Setting:
send midi: if activated, the app won't play any note but will send midi with the source name "MusicalBox". Use a virtual instrument to get the midi notes and play them.

octave: translate notes to an octave

instrument: select an instrument sound

scale: select a scale (minor, major, etc.)

Step 3: Play It!

And share your suggestions.
<p>Just found this and love the simple DIY approach. I want to do this with my students. The link to the app didn't work for me. Do you have an updated link? Thanks.</p>
Haven't had chance to try this yet, but I would think it would be great to convert this to an ios app to make the music box more portable.
