6. The Edison phonograph -- 1878 Much of Edison's most important work was done while he was very young. Here he is shown with an early form of the wax-cylinder phonograph, April 1878. The photo was taken when Edison appeared before the National Academy of Science meeting held in the Smithsonian Institution, April 1878. http://scienceservice.si.edu/2478/011014.jpg

11. Leon Theremin http://www.137.com/theremin/leon_theremin300c.jpg Perhaps the most intriguing characteristic of the theremin – apart from its mysterious sound – is the way it is played: — There are no keyboards, — no finger boards, — no strings, valves, hammers or pipes. — There is nothing to blow on, or into. The performer literally “plays the air” around the instrument, making absolutely no physical contact with it.

15. The New York Electric Music Company and The Second Telharmonium (or Dynamophone) The first performances of this Telharmonium (or as Cahill called it the Dynamophone) were made from the Cabot Street Mill workshop and were transmitted to the Hotel Hamilton about a half-mile away. Later, in 1904, Cahill made a transmission from Holyoke to New Haven Connecticut. In 1905 Crosby established another corporation, this one in New York City (the New England Electric Music Company was established in New Jersey). He made a deal with the New York Telephone Company to lay special lines so that he could transmit the signals from the Telharmonium throughout the city. http://audiolib4.free.fr/wikino/index.php?page=teleharmonium

37. It is difficult, almost impossible, to redefine an instrument as familiar as the piano, but Henry Cowell did so by reaching into it and using the strings to manipulate his playing. http://assets.mog.com/pictures/wikipedia/87062/Henry_Cowell.jpg http://i298.photobucket.com/albums/mm247/magicistragic/Cowell2ir.jpg
