- n. An instrument for producing music (Tel*har"mo*ny [�]), at a distant point or points by means of alternating currents of electricity controlled by an operator who plays on a keyboard. The music is produced by a receiving instrument similar or analogous to the telephone, but not held to the ear. The pitch corresponds with frequency of alternation of current.
Sorry, no etymologies found.
It was the music feature of this party that was distinctive; it was supplied by wire through an invention known as the telharmonium which, it was believed, would revolutionize musical entertainment in such places as hotels, and to some extent in private houses.
He did not dwell on the failures, but he told how he had been the first to use a typewriter for manuscript work; how he had been one of the earliest users of the fountain-pen; how he had installed the first telephone ever used in a private house, and how the audience now would have a demonstration of the first telharmonium music so employed.
Just why the telharmonium has not made good its promises of popularity I do not know.
Examples of electromechanical sound producing devices include the telharmonium, Hammond organ, and the electric guitar.
