Music Box Composer

By Jelly Biscuits

Open iTunes to buy and download apps.


Create your own Music Box music, and easily share your compositions with others.

Designed to aid composing your own music prior to punching the paper strips for Music Boxes, MBC allows you to compose, preview, play, save and share your creations via Twitter, Facebook, Email or iTunes file transfer.

A small but growing library of Music Box Strips can be viewed here, via webplayer or loading into MBC on device:

Demo of composing, printing, punching an playing:

- Supports 15, 20 and 30 note music boxes.
- Share your compositions with others via Facebook, Twitter and Email.
- Multiple undo
- Disable Notes for temporary changes
- Ripple edits
- Save and Load (access the save location via iTunes File Sharing)
- Sounds sampled from physical Music Boxes
- Save strip to PDF/JPG file.

The physical Music Boxes with the paper punch strips and are great fun - what I found was missing was an easy way to preview either transpositions or original creations. This aims to fill that gap but it's also a fun music creation tool in it's own right.

Rated as a Killer App by Apps4iDevice.

Note that there is a desktop version of MBC available from the Mac App Store, as well as desktop versions for other OS's from the Jellybiscuits site.

What's New in Version 2.50

Support for the 33 note music box has been added.

Dragging a note off the strip to delete has been reinstated.

Converting between strip sizes has been improved.

Fonts updated for more complete character support.

Miscellaneous bug fixes.

Wonderful app! If you are composing for music box and you're a perfectionist like me, this app is absolutely essential. A real joy to work with. The best part is you do not need to know how to read music, but it definitely helps to have an ear for it. Recommend spending some time in help mode reading all of the pop ups. Once you are familiar with the buttons/functions (all of which you will use at some point) the flow is very natural. Bravo!


It provides a fun way to work out harmonic and rhythmic ideas very quickly. I've written close to 100 short tunes, many of which are in 3 because, well, it's a music box.
MBC could use an update (according to my ipad) to make it work better with the current OS. Maybe it's a memory hog since it does crash quite often. Helps if you save work as you go.
Thanks for a nice app.

Here's the fix if you have no sound!

Turn off your mute/ringer switch on the side of your phone. That fixes it.

Great app, really wish their was a user guide. The tutorial is very small/basic and the program is difficult to learn.
