The public had to be taught the principle and function of the telephone. Gardner Hubbard, Bell's father-in-law, arranged a series of lectures to be given by Bell and Watson. The first demonstration was given before the Essex Institute of Salem, in 1877. Watson, in Boston, played musical instruments and sang. The audience was delighted. By courtesy of Mann & Company. From the Scientific American of March 31, 1877.
