English: Tin foil, 1870s.
Tin foil was the first material successfully used to record music. It was soft enough for delicate sound waves to be etched into its surface, yet hard enough to be traced over with a needle to play back the sounds. But it wasn’t perfect. Tin foil ripped, and it could be played only a few times before the groves wore down.
