Overview of Electronic Musical Instruments
Techniques for producing musical sounds by purely electrical (nonacoustic) means have been known for many years. One of the earliest was the telharmonium, invented by Thaddeus Cahill during the first decade of the twentieth century. The device employed rotating toothed wheels that imparted their signals to electromagnets placed in proximity. Various tones could be combined in harmonic relationships, and complex signals could be produced and transmitted directly over telephone lines.
