A day like today… but from 1877 Edison shows the phonograph for the first time

edison phonographA day like today November 29, but from 1877 Thomas Alva Edison shows the phonograph for the first time.

The phonograph It was the first device capable of recording and reproducing sound.. This uses an analog mechanical recording system in which sound waves are transformed into mechanical vibrations by means of an acoustic-mechanical transducer. These vibrations move a stylus that carves a helical groove on a phonograph cylinder. To play the sound, the process is reversed.

At first, tin-coated cardboard cylinders were used, later of waxed cardboard and, finally, of solid wax. The wax cylinder, of higher quality and durability, had been on the market since 1889, a year after the gramophone appeared. This was another device but one that used a flat disc.

On December 2, 1889, a representative of the Edison house, Theo Wangeman, recorded a performance by the renowned composer Johannes Brahms. It was a segment of the Hungarian Dances in a version for solo piano. This recording is still preserved, but its quality is terrible.

Since 1877 multiple artifacts similar to the phonograph were developed and the so-called “talking machines” arose. However, only the gramophone succeeded in overshadowing Edison’s invention.

In 1888, Emile Berliner patented the gramophone, an instrument very similar to the phonograph that was used to add sound to motion pictures and was the starting point for CBS (Columbia Broadcasting System).
