A phonograph was the first invention in the world that can record sound and play it back to the audience in the right order. People at the time were amazed by the technology and used it for many purposes. In the first two chapters of “WHAT  MR. OPENEER HEARD ”, the author emphasized that people enjoy phonographs a lot as an entertainment. People used phonographs to listen to music with friends which wasn’t possible before without a live band and singer. People could freely choose songs and singers at anytime, locations and can repeat it over and over again. The author also mentioned in the article that phonographs were also used to preserve memories of the past and the deceased. Aside from a form of entertainment, phonograph was also used for dictation at offices. Phonographs allowed workers to work more efficiently which helps companies save money, Despite its similarities to the recording nowadays, phonographs had many flaws in its designs which were limiting its potential. First, the author mentioned people’s attempts to use phonograph to give a speech. All the attempts failed because phonographs simply could record and play back words at a accurate, fast and loud rate. The limitation of phonographs were also due to their fragility. All the recordings were done on a wax cylinder which is very fragile and easily damaged. Although phonographs were somewhat useful for people at the time for entertainment and dictation, it certainly did not live up to people’s expectations when it first came out.
