key is G major in Mixolydian mode, and the time signature throughout is 4/4. Its structure comprises an intro, two verses and a chorus, followed by a third verse and repeated choruses. From its opening chord of G major, the verses introduce a VII/I (Fadd9/G), a chord change that constitutes a pedal point on G (sustained harmonic tone) and so recalls some of the Beatles' Indian-inspired melodies from Revolver. Among musicologists, Everett says that from the seventh bar of the verse, C major is revealed as the true key, whereas Alan Pollack writes that the emphasis given to C major at the end of the musical phrases instead suggests "a perilously high center of gravity with respect to G being the home key". The Indian influence is heightened on the band's recording of the song through the use of gamak melodies in the accompaniment. Pollack considers a notable aspect of the chorus to be the bass move from C to G via a III (B). According to MacDonald, the song's loose, swinging rhythm, which he describes as "chugging pseudo-march", suggests the influence of the Four Tops' 1966 hit single "Reach Out I'll Be There". Author and critic Kenneth Womack comments that the lyrics appear to "address issues of wealth and celebrity" for listeners unfamiliar with the countercultural concept of "beautiful people". The song reflects the Beatles' disdain for consumerism and materialism, a theme that, inspired by the band members' use of the hallucinogenic drug LSD, they introduced in the lyrics to Revolver tracks such as "And Your Bird Can Sing". Authors Russell Reising and Jim LeBlanc highlight the lines "You keep all your money in a big brown bag inside a zoo / What a thing to do" as particularly dismissive of the acquisition and hoarding of material wealth. The same authors recognise an element of ridicule towards some of the "beautiful people", specifically those that, in Lennon's words, travel no further than "As far as the eye can see" and, even then, see "Nothing that doesn't show". Music critic Tim Riley identifies a droll quality in the answers that Lennon provides to his own questions. With regard to the song's message, he writes: "It's clear that they understand their position: if the Beatles are beautiful people, by extension their listeners become beautiful people ('Baby, you're a rich man, too')."
