"The Telephone Hornpipe" is an American hornpipe in D Major. The parts are played AABB. In 1876, Scottish emigrant Alexander Graham Bell was the first to be granted a United States patent for a device that produced clearly intelligible replication of the human voice. On March 10th 1876 the first successful telephone transmission of clear speech using a liquid transmitter when Bell spoke into his device, "Mr. Watson, come here, I want to see you." and Watson heard each word distinctly. In 1877 the first permanent outdoor telephone wire was completed. It stretched a distance of three miles. This was closely followed in the U.S. by the worlds first commercial telephone service. In 1878 the workable exchange was developed, which enabled calls to be switched between subscribers rather than having direct lines. Some time after these events an unknown musician composed "The Telephone Hornpipe" to celebrate the significance of the invention. "The Telephone Hornpipe" was printed in Ryan’s Mammoth Collection (1883) and Cole's 1000 Fiddle Tunes (1940).
