track, consisting of guitars, piano and drums, at EMI Studios (now Abbey Road Studios) in London. The session took place on 2 June 1966, the day after Harrison met Indian classical musician Ravi Shankar for the first time and secured Shankar's agreement to help him master the sitar. The band recorded five takes of the song before Harrison selected the third of these for further work. After reduction to a single track on the four-track master tape, their performance consisted of Harrison on lead guitar, treated with a Leslie effect, McCartney on piano and Ringo Starr on drums, with Lennon adding tambourine. The group then overdubbed vocals, with McCartney and Lennon singing parallel harmony parts beside Harrison's lead vocal. Further overdubs included maracas, the sound of which Pollack likens to a rattlesnake; additional piano, at the end of the bridge sections and over the E79 chord in the verses; and handclaps. Created during a period when the Beatles had fully embraced the recording studio as a means of artistic expression, the recording added further to the message behind the song. Like "Eight Days a Week", the completed track begins with a fade-in, a device that in combination with the fadeout, according to Rodriguez, "provided a circular effect, perfectly matching the song's lack of resolution". Everett similarly recognises McCartney's "clumsy finger-tapping impatience" on the piano over the E79 chord as an apt expression of the struggle to articulate. The final overdub was McCartney's bass guitar part, which he added on 3 June. The process of recording the bass separately from a rhythm track provided greater flexibility when mixing a song, and allowed McCartney to control the harmonic structure of the music by defining chords. As confirmed by the band's recording historian, Mark Lewisohn, "I Want to Tell You" was the first Beatles song to have the bass superimposed onto a dedicated track on the recording. This technique became commonplace in the Beatles' subsequent work. During the 3 June session, the song was temporarily renamed "I Don't Know", which had been Harrison's reply to a question from producer George Martin as to what he wanted to call the track. The eventual title was decided on by 6 June, during a remixing and tape-copying session for the album. Release and reception EMI's Parlophone label released Revolver on 5 August 1966, one week before the Beatles began their final North American tour. "I Want
