So people, I'm back with new and fresh info.

Today, my topic is Electronic Music of the late 19th century to early 20th century.

  The ability to record sounds is often connected to the production of electronic music, but not absolutely necessary for it. The earliest known sound recording device was the phonautograph, patented in 1857 by Édouard-Léon Scott de Martinville. It could record sounds visually, but was not meant to play them back.

  In 1878, Thomas A. Edison patented the phonograph, which used cylinders similar to Scott's device. Although cylinders continued in use for some time, Emile Berliner developed the disc phonograph in 1887.A significant invention, which was later to have a profound effect on electronic music, was Lee DeForest's triode audion. This was the first thermionic valve, or vacuum tube, invented in 1906, which led to the generation and amplification of electrical signals, radio broadcasting, and electronic computation, amongst other things.
