An instrument similar to a harp, in the sense that it has dozens of strings, but is rather small in size and has buttons that change the sounds so you can play different chords all across the strings by strumming. When you press a chord button, it presses down a long rod with pieces of felt attached. The pieces of felt press down on strings of which are not used for the particular chord and leaves certain strings free to sound for that particular chord.
