Paul Theberge states in ‘The Cambridge Companion To Pop and Rock’; “without electronic technology, popular music in the twenty first century is unthinkable.” In 1828 Sir charles Wheatstone constructed a rudimentary devise for amplification of sound called a ‘microphone’. Emile Berlner in 1876 developed a ‘loose contact transmitter’ to increase volume in the Microphone; allowing the development of ‘String Bass’ before this the tuba was what gave the ‘bass effect’.
Amplification developed in 1904 by Lee De Forest, meant that singers such as Elvis had ability to be influential. ‘1950’s amplification becomes a necessary part of the establishment of Rock ‘n’ Roll.’ (Straw & Street, 2001) Amplification makes music more accessible.
Popular music can be unplugged, however, it couldn’t be defined as “popular” “enjoyed by a large number of people” as it wouldn’t be reached by a large audience, it could be considered popular within a smaller community.
