Playing this harp is easy – simply wave your hands through the beams. When the visitor breaks the beams, professional quality sounds resonate from the external speaker. The Laser Harp gives visitors the chance to create their own musical masterpiece, even if they have never played an instrument before. Visitors can chose from many preprogrammed sound patches. Each patch has its own unique sonic character and can be cycled through by pushing the button located on the harp’s throat.
