Freed from the burden of touring, the Beatles embraced an increasingly experimental approach as they recorded Sgt. Pepper’s Lonely Hearts Club Band , beginning in late November 1966. According to engineer Geoff Emerick , the album’s recording took over 700 hours. He recalled the band’s insistence “that everything on Sgt. Pepper had to be different. We had microphones right down in the bells of brass instruments and headphones turned into microphones attached to violins. We used giant primitive oscillators to vary the speed of instruments and vocals and we had tapes chopped to pieces and stuck together upside down and the wrong way around.” Parts of ” A Day in the Life ” featured a 40-piece orchestra.
