Karsy’s Giant Myriphon. Musical Instrument. 1901. NYC.
“Mr. and Mrs. Karsy, an inventive and original “team” on the variety stage, have created a new and extrodinary musical instrument which is known as the Giant Myriophone (Myriphon). It is the work of a genius and when under full swing produces music similar to that of a full string band. Only two persons are required to produce this immense volume of sound.
“The Myriophone has the appearance of a large screen, with a number of wheels fitted on the front. These wheels have strings fitted on them and look much like bicycle wheels. They are set in motion by four lusty stage hands concealed in the rear, and the performers who have a small stick of wood in each hand touch the strings, thus making a note, which can be prolonged to any length. The Myriophone consists of twenty-five discs, each with eighty strings, making 2,000 in all. The sounding boards are made of the same wood as is used in pianos. Regular piano strings are used.”
