Transcript of Music Timeline
Graham Bell's graphophone. The graphophone used
wax cylinders which could be played many
times, however, each cylinder had to be recorded separately
making the mass reproduction of the same music
or sounds impossible with the graphophone. Edison was working on a machine that would transcribe telegraphic messages through indentations on paper tape, which could later be sent over the telegraph repeatedly. The machine had two diaphragm-and-needle units, one for recording, and one for playback. Thomas Edison invented the Phonograph in 1877. On November 8 1887, Emile Berliner, a
German immigrant working in Washington
D.C., created a Musical Recording Device
that played music with circular records.
Berliner's disks (records) were the first sound
recordings that could be mass-produced by
creating master recordings from which molds
were made. From each mold,
hundreds of disks were pressed. 1887 - Emile Berliner Invents
The Gramophone And Records These devices have large memory and can store many hundreds of songs, whilst also being touch screen. Today we have musical devices that you can
play games and apps on and that play music
out of either speakers or headphones The magnetic recording was demonstrated in principle as early as 1898 by Valdemar Poulsen in his telegraphone. Magnetic wire recording, and its successor, magnetic tape recording, involve the use of a magnetizable medium which moves past a recording head. An electrical signal, which is analogous to the sound that is to be recorded, is fed to the recording head, inducing a pattern of magnetization similar to the signal. A playback head (which may be the same as the recording head) can then pick up the changes in the magnetic field from the tape and convert them into an electrical signal.
