Harrison served as the Beatles' scout for new American releases, being especially knowledgeable about soul music. By 1965's "Rubber Soul", he had begun to lead the other Beatles into folk rock through his interest in the Byrds and Bob Dylan, and towards Indian classical music through his use of the sitar on "Norwegian Wood (This Bird Has Flown)". He later called "Rubber Soul" his "favourite [Beatles] album". "Revolver" (1966) included three of his compositions: "Taxman", selected as the album's opening track, "Love You To" and "I Want to Tell You". His drone-like tambura part on Lennon's "Tomorrow Never Knows" exemplified the band's ongoing exploration of non-Western instruments, while the sitar- and tabla-based "Love You To" represented the Beatles' first genuine foray into Indian music. According to the ethnomusicologist David Reck, the latter song set a precedent in popular music as an example of Asian culture being represented by Westerners respectfully and without parody. Author Nicholas Schaffner wrote in 1978 that following Harrison's increased association with the sitar after "Norwegian Wood", he became known as "the maharaja of raga-rock". Harrison continued to develop his interest in non-Western instrumentation, playing swarmandal on "Strawberry Fields Forever".
