History: Early Years Of The Beatles

The Beatles made innovative use of technology, treating the studio as an instrument in itself. They urged experimentation by Martin and their recording engineers, regularly demanding that something new be tried because "it might just sound good". At the same time they constantly sought ways to put chance occurrences to creative use. Accidental guitar feedback, a resonating glass bottle, a tape loaded the wrong way round so that it played backwards—any of these might be incorporated into their music. The Beatles' desire to create new sounds on every new recording, combined with Martin's arranging abilities and the studio expertise of EMI staff engineers such as Norman Smith, Ken Townsend, and Emerick, all contributed significantly to their records from Rubber Soul and, especially, Revolver forward. Along with studio tricks such as sound effects, unconventional microphone placements, tape loops, double tracking and vari-speed recording, they augmented their songs with instruments that were unconventional for rock music at the time. These included string and brass ensembles as well as Indian instruments such as the sitar in "Norwegian Wood (This Bird Has Flown)" and the swarmandal in "Strawberry Fields Forever". They also used early electronic instruments such as the Mellotron, with which McCartney supplied the flute voices on the "Strawberry Fields" intro, and the clavioline, an electronic keyboard that created the unusual oboe-like sound on "Baby, You're a Rich Man".
Legacy
The Beatles' influence on popular culture was—and remains—immense. Former Rolling Stone associate editor Robert Greenfield said, "People are still looking at Picasso ... at artists who broke through the constraints of their time period to come up with something that was unique and original. In the form that they worked in, in the form of popular music, no one will ever be more revolutionary, more creative and more distinctive." From the 1920s, the United States had dominated popular entertainment culture throughout much of the world, via Hollywood movies, jazz, the music of Broadway and Tin Pan Alley and, later, the rock and roll that first emerged in Memphis, Tennessee. The Beatles not only triggered the British Invasion of the US, but themselves became a globally influential phenomenon.
