Give the chord progression and a style and JChordBox generates a song. JChordBox is a library tool that can generate backing tracks from a chord progression and a music style. A music Style is describe using an XML and a MIDI file. You can generate an XML Style file from a MIDI file by adding markers to delimit grooves. An XML Song file describes a chord progression and sets the music style to use. JChordBox comes with several command line tools (GenerateSong, CreateStyleFromMidiFile, SongPlayer …). NEW:The application center is called SongPlayer and is a text based user interface that can play JChordBox song.

This project was started as a Masters project back in 2006. I completed the project as part of my dissertation, and produced software to render Maya script (MEL) to animate a piano model I'd also created. From this I produced a number of videos, which I uploaded periodically to YouTube. Following numerous request I attempted to create a standalone application to playback MIDI performances without the need for a 3rd party 3d modelling/rendering application such as Maya. Given my original background in Java, and it's existing support for MIDI files, I proceeded to attempt to create this using Java 3D. However, (and this sounds like an excuse, which it probably is), life got in the way and I never completed the project to a commercial standard for reproduction. As such, I'm offering the source here in good will to other developers/musicians who might be able to take what I've achieved and carry it forward to a useful learning tool.
