Lecture 2 Early Sound Recording Rhythm & Blues (Chicago Blues) Early Sound Recording • Thomas Edison invented sound recording in 1877 • His phonograph was acoustic (mechanical): sound engraved on a tin cylinder • Alexander Graham Bell’s graphophone (1885) replaced tin with wax: improved sound quality • Emile Berliner: develops the gramophone from 1888-1896 • Replaces cylinder with flat disc, the format that eventually replaced cylinder • A problem with early recording: performers had to be close to the horn to maximize sound Electrical Recording • Ca. 1925 electrical recording increases the sonic accuracy of records • For the first time, it became possible to record performances of orchestras etc. • Electric record players soon became commercially available: improved sound Formats • 78 rpm disc: limit of four minutes per side • 33 rpm disc: introduced 1948, expands limit to 20 minutes per side • Uses vinyl, rather than shellac: quieter, better sound again
