Matthew Ewing English 102 Professor Slaven February 7, 2013 The Evolution of Music Players An Annotated Bibliography You don’t need this title. My paper will contain an overview of the evolution of music players in past history up until present day. I will elaborate on the way music players were used, and how they vary from culture to culture. Music players are the driving force behind music. Music players provide sound for people to hear and interpret the music. Music would not exist without music players. There has to be some type of device or tool that is being used for sound to be available. The history of music players began in the late 1850s, when the first ever attempt to record sound signals was successful. These methods included the recording of arbitrary sounds involving the living recording of a performance. This entirely mechanical process was called acoustical recording. The sound of the performers was captured by a “diaphragm” with the cutting needle connected to it. The needle made the groove in the recording medium. To make this process as efficient as possible the diaphragm was located at the apex of a cone and the performers would crowd around the other end. In 1875 Edouard-Leon invented the phonautograph. The phonautograph was a device that could record sound waves as they passed through the air. After test and analysis, he found that the sound waves could not playback the sound. Because it was only intended for visual study (notes taken as sound waves travel through air). Later in 1877 another inventor, Charles Cros suggested that the process could be reversed by the photoengraving to change the trace line into a groove that would guide the stylus, passed on to the linked diaphragm then sent back into the air. That made all the difference because slight sound could actually be heard from the phonautogroah. A new invention was made
