The Lord of the Rings Online: Shadows of Angmar has a music system that allows you to play your own music while in the game. Characters that have reached level 5 can learn to play one or more instruments depending on their class. Instruments can be purchased from a Bard. When you put the instrument in your ranged weapons slot and use the /music command, the player will be put into music mode. You can play the instrument in real time on two octaves, using the 1-8 number keys.
