Styrophone

The musical Styrophone is a type of friction idiophone created by Robert Rutman in the 1990s as a parody of his well-known sheetmetal instrument, the Bow Chimes. It consists of a foam box from which protrude a series of thin brass rods played with a violin bow. Rutman's ensemble would build the impromptu instruments prior to a performance, and then destroy them through the process of their use.^[1] Other versions have been created with wooden sticks used in place of metal.^[2]

An inexpensive alternative to heavy-duty amplification systems, the Styrophone loudspeaker is usually of a cheap homemade variety that consists of a crystal earpiece attached to a cone made from a foam cup or sections of packing material.^[3]
