The basic track, and Lennon's guide vocal (which is used in the master), were recorded at Trident Studios on 22 February, shortly after shooting for the Let It Be film ended. The song, initially titled "I Want You", was rehearsed several times during the Get Back/Let It Be sessions, with the first one being on 29 January 1969 at Apple Records. In the middle of the 15th repetition of the theme, the song abruptly ends. The song's coda consists of a three-minute repetition of the "She's So Heavy" theme, with the arpeggios double tracked, intensifying with "white noise" fading in as the theme continues, which consists of multi-tracked guitars from Lennon and George Harrison, Moog white-noise from Lennon, and drums and bass from Ringo Starr and McCartney respectively. During the next E 7( ♭9) transition, Lennon lets loose a primal scream of "Yeah", until his voice breaks. Another repeat of the "She's So Heavy" theme (this time featuring harmonies) is followed by Lennon singing a livelier repeat of the "I Want You" verse.

The second set of verses are rendered instrumentally with lead guitar. The main theme repeats with Lennon singing "She's so heavy", with a long sustain on the last word. That functions as a transition to the main theme throughout the song. " The two blues verses alternate, before the reappearance of the E 7( ♭9) chord, and McCartney playing a notably aggressive bass riff. As the last chord fades, a verse begins in 4Ĥ time, based on the A and D blues scales, with Lennon singing "I want you / I want you so bad. The bass and lead guitar ascend and descend with a riff derived from the D minor scale. In this chord sequence, the F note is a drone. It begins in 6Ĩ time, with an arpeggio guitar theme in D minor, progressing through E 7( ♭9) and B ♭ 7 before cadencing on an A augmented chord. Lennon wrote the song about his love for Yoko Ono. It was the first song recorded for the Abbey Road album but one of the last songs to be finished the band gathered in the studio to mix the song on 20 August 1969, marking the final time that all four Beatles were together in the studio. The song closes side one of their 1969 album Abbey Road and features Billy Preston playing the organ.
