"Well, it seems that Turbine has created a player generated music system for LoTRO: Shadows of Angmar. Players may buy instruments – such as flutes, lutes and drums, and play together to create music. All I could think of was… What an amazing concept!"I haven't even bothered about Lord of the Rings online before, but hearing about this feature in the game where you can enter music mode and play a variety of musical instruments, made me really interested. You can play 24 different notes by using the 1-8 numerical keys on your keyboard, and holding down either Ctrl or Shift.
