lyrics with bluesy tone and harmony rather than creating tunes that made striking shapes of their own." MacDonald praises Harrison's lead guitar work for the role his "characterful lines and textural colourings" play in supporting Lennon and McCartney's parts, and describes Starr as "the father of modern pop/rock drumming". Influences The Beatles' earliest influences include Elvis Presley, Carl Perkins, Little Richard and Chuck Berry. During the Beatles' co-residency with Little Richard at the Star-Club in Hamburg, from April to May 1962, he advised them on the proper technique for performing his songs. Of Presley, Lennon said, "Nothing really affected me until I heard Elvis. If there hadn't been Elvis, there would not have been the Beatles."

Reflecting the range of styles they explored, Lennon said of Beatles for Sale, "You could call our new one a Beatles country-and-western LP", while Gould credits Rubber Soul as "the instrument by which legions of folk-music enthusiasts were coaxed into the camp of pop". Although the 1965 song "Yesterday" was not the first pop record to employ orchestral strings, it marked the group's first recorded use of classical music elements. Gould observes: "The more traditional sound of strings allowed for a fresh appreciation of their talent as composers by listeners who were otherwise allergic to the din of drums and electric guitars." They continued to experiment with string arrangements to various effect; Sgt. Peppers "She's Leaving Home", for instance, is "cast in the of a sentimental Victorian ballad", Gould writes, "its words and music filled with the clichés of musical
