jfugue2me
The adaptation of JFugue library for J2ME
It allows you to use JFugue-2.1 API to program music on MIDP 2.0, CLDC 1.1 compatible mobile devices.
It's easy to use, like this code to play C-major scale:
Player player = new Player();
player.play("C D E F G A B");
It's all based on JFugue-2.1 sources, so go to http://www.jfugue.org for more information.
