n. 1. 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.

Tales of technology passed. (Up Front)
In 1995, the science-fiction writer Bruce Sterling, whose body resides most of the time in Austin, Texas, posted a message on the Web inviting people to write what he called "The Handbook of Dead Media," an exercise in "media forensics" or (varying the metaphor) "a naturalist's field guide for the communications paleontologist." The idea was to track the history of the once-vibrant but now forgotten, the junk store of silenced communications along the road of obsolescence: the phenakistoscope, the teleharmonium, the stereopticon, the Telefon Hirmondo, the Antikythera Device, and a thousand more gadgets and extensions of human experience that once lived and do so no more.
