phonoautograph
the earliest known device that enabled the recording of music was the phonoautograph invented in 1857 by Édouard-Léon Scott de Martinville,The device worked by funneling sound through a horn and then over a thin membrane, which was stretched tight like a drum. The membrane was attached to a small reed that engraved an image of the sound waves into a hand-cranked cylinder. While this device did not allow the user to play back the recording, taken from (http://illumin.usc.edu) -
phonograph
in 1877 thomas edison used the idea of the phonoautograph to create his own version of it, and called it the phonograph, he used the same concept of the phonautograph but made some changes that allow the device to replay the recorded sound -
more changes of edison
However, Edison's creation could also replay the audio through a reverse process. To replay, the needle would move based on the scratches in the rotating cylinder, vibrating the membrane to produce a sound that was amplified through a large horn. These cylinders were eventually replaced with 7-16 inch diameter flat discs called albums or records, taken from (http://illumin.usc.edu) -
vynil albums
in 1889 the structure of the gramophone changes again and the cylinder in which the music was recorded change to a flat vynil disc that rotated beneath the recording needle, nowadays some people continue using this type of reproduction because of the quality of sound that is thaks to the converted types of vibration that are used to record the sound, hs received only a feww changes through the time -
cassette tapes
Commercialized in the late 1940s by John T. Mullin and pitched to Hollywood as a novel way to record movie soundtracks,. Because of the high quality of the recording and the space of storage (a tape can be used from both sides), actors were free from the pressure of live performance, the recording of diverse audio and also video in this inventions enable them to become popular nd widely-used throughout homes and inside automobiles. -

future
all depend of the improvements that could be made and that music lovers can propose, with the new styles of music, new ways to hear it can be created, phonoautograph was for opera, cassette was for rock and roll and balades, so we can wait to be surprised by the changes of music industry or be the ones that surprise others with new things or improving something,
