A laser harp is an electronic musical instrument consisting of several laser beams to be blocked, in analogy with the plucking of the strings of a harp, in order to produce sounds. The laser harp has been popularized by Jean Michel Jarre, and has been a high profile feature of almost all his concerts since 1981. In recent times, a very similar version has also been used in concerts by British electronic musician Little Boots.
