There are reports of other methods, probably based on the action of wind or forced air, dating as far back as about 1500 bce, in the 18th dynasty of ancient Egypt, when a colossal statue of the god Memnon at Thebes made some sort of sounds to greet his mother, the goddess of the dawn. Until the end of the 19th century, music was reproduced primarily by means of the mechanical method. In both cases, the resulting sound is expected to be that of the independent performance. ![]() In the acoustical and electrical methods of reproduction, sonic vibrations themselves are captured in performance and reproduced-by purely mechanical means in the acoustical method and by the use of vacuum tubes, transistors, and other such devices in the electrical. In the mechanical, an automatic instrument, such as the barrel organ, plays music that has been built, or programmed, into the mechanism by the designer the resulting sound is that of the apparatus. The physical reproduction of music has been accomplished in three major ways, which can be designated the mechanical, the acoustical, and the electrical. ![]() For information on the former method see notation. This article concerns itself solely with the latter, nonsymbolic, method. Signals, on the other hand-being direct physical impressions of, and potential stimuli to, sounds-bypass the performer in their reproduction and, in some electronic compositions, even in their recording. In notation, symbols are written down as a message to a trained performing musician who understands them and reinterprets them into sound. The former-musical notation-matured earlier, and in one form or another it virtually monopolized the recording of music for centuries the latter had to await the emergence of technology for its development. The efforts to capture the fleeting sounds of music have followed two basic methods: that of symbols and that of signals. Music recording, physical record of a musical performance that can then be played back, or reproduced.īecause music evaporates as soon as it is produced, humans, seeking permanence in life’s ephemera, have long sought ways to record and reproduce it.
