  Making innovative use of technology while expanding the possibilities of recorded music, the Beatles urged experimentation by Martin and his recording engineers. Seeking 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. Their desire to create new sounds on every new recording, combined with Martin's arranging abilities and the studio expertise of EMI staff engineers Norman Smith, Ken Townsend and Geoff Emerick, all contributed significantly to their records from Rubber Soul and, especially, Revolver onwards.
  
  Along with innovative studio techniques such as sound effects, unconventional microphone placements, tape loops, double tracking, and vari-speed recording, the Beatles augmented their songs with instruments that were unconventional in rock music at the time. These included string and brass ensembles as well as Indian instruments such as the sitar in "Norwegian Wood" and the swarmandal in "Strawberry Fields Forever". They also used novel electronic instruments such as the Mellotron, with which McCartney supplied the flute voices on the "Strawberry Fields Forever" intro, and the clavioline, an electronic keyboard that created the unusual oboe-like sound on " Baby, You're a Rich Man ".
