Its composition was an attempt by Lennon at writing a song in the style of Motown star Smokey Robinson, specifically his song "I 've Been Good To You '', which has similar circular doo - wop chord changes, melody and arrangement. The tune and arrangement also draws from "You Do n't Understand Me '', a B - side to a Bobby Freeman single. Paul McCartney cites the Teddy Bears ' 1958 hit "To Know Him Is To Love Him '' as also being influential. Lennon, McCartney, and George Harrison join together to sing an intricate three - part close harmony in the verses and refrain (originally the middle eight was conceived as a guitar solo, but altered during the recording process) and a similar song writing technique is exercised in later Beatles songs, such as "Yes It Is '' and "Because ''. The song, in D major, revolves around a 1950s - style I - vi - ii - V doo - wop sequence in 12 / 8 time before moving to the harmonically complex middle eight (G-F # 7 - Bm - D7 - G - E7 - A-A7) and back again for the final verse and fade - out. William Mann describes the song as, "harmonically... one of their most intriguing, with its chains of pandiatonic clusters ''
