Here, I will focus on the instrumentation and other technical details of The Beatles' eighth album (Britsh Release):

Overall: Recorded between December 6, 1966 and April 3, 1967, with the gibberish at the end recorded on April 21. Released on June 1, 1967. This was the first album recorded since the Beatles retired from touring, and it shows that their efforts are entirely devoted to the studio. It was also the first one not to be butchered by US record companies. It was recorded with the idea of mimicking a live performance to some extent, and the space between tracks on the album were smaller than any before it. It took more than 700 hours and $75,000 to complete Sgt. Pepper. To give a radically new feel, all vocals and instruments were recorded with at least some sort of studio manipulation, and the studio was a laboratory of sorts for sound experimentation.

  1. Sgt. Pepper's Lonely Hearts Club Band...Recorded on February 1, 1967 at Abbey Road, with overdubs on February 2 and March 3 and 6. This marked the first time a bass drum was tampered with in order to produce an effect with any musical value of its own. This is common practice nowadays. Audience sounds were dubbed in to simulate live performance.

  7. Being for the Benefit of Mr. Kite!...Recorded on February 17, 1967 at Abbey Road, with overdubbing February 20 and March 28, 29, and 31.

  13. A Day in the Life...Recorded on January 19, 1967(basic track -- Lennon and McCartney on guitar and piano) and on Febeuary 10, 1967 (orchestral track) at Abbey Road, with the one-chord ending overdubbed February 22. Lennon's voice is recorded with tape echo. During the middle McCartney part, Mal Evans' voice can be heard counting keeping time by counting off the bars as he stood by the piano. He set an alarm clock to go off after twenty-four bars, and that can be heard too. McCartney wanted an orchestra to "freak out" during the connecting bars, and Lennon wanted the sound to rise up and "sound like the end of the world". The result was a forty-one piece orchestra. The score Martin wrote called for each instrument to go from its highest to lowest note possible in twenty-for bars. McCartney instructed the musicians to play as out of tune and out of time as possible, and repeated tries were needed to get the desired chaos. The final piano chord needed to last as long as possible, and the recording equipment was turned up so high about twenty-four seconds into it, that the studio's air conditioners were audible. The chord was played on three pianos which were struck as hard as possible simultaneously. The Mellotron, a keyboard that electronically produces programmed taped sounds, was used for the first time ever , and would later be standard for rock bands.
    • McCARTNEY: lead vocals on the middle section, piano on basic track, bass, three pianos at the end of orchestral track, conducts the 41-piece orchestra
    • LENNON: lead vocals, Gibson J-160E acoustic guitar on basic track, lead guitar at the beginning of orchestral track, three pianos at the end of orchestral track
