Recording , features prominently on the Beatles' recording. The Beatles recorded the basic track for "Piggies" at EMI Studios (now
Abbey Road Studios) in London on 19 September 1968. After Harrison had performed the song alone on the Esher demo – playing acoustic guitar and whistling over the solo – the use of harpsichord on the official recording came about through happenstance. Acting as a producer in
George Martin's absence on some of the White Album sessions,
Chris Thomas noticed the instrument set up in preparation for a later session, for a classical recording, in EMI's Studio 1. Harrison agreed that a harpsichord part would suit the song, and so the Beatles' session was moved from Studio 2. The group taped eleven takes of "Piggies" before achieving the requisite performance. The line-up was Harrison on acoustic guitar, Thomas on harpsichord, McCartney on bass and
Ringo Starr on tambourine. Lennon was present at the session but, with only
4-track recording facilities available in Studio 1 (and the available tracks taken up by the other four musicians), he did not play on the basic track. Having attended London's
Royal Academy of Music as a child, Thomas performed the harpsichord solo in an authentic classical style, according to Pollack, who highlights how "the melody played by the last three fingers [of the right hand] alternates with a repeated note played by the thumb".
Overdubbing On 20 September, the recording was copied over to 8-track tape in Studio 2, to allow for
overdubbing. Harrison then added his lead vocal, together with harmony vocals on the last verse, creating a mock
operatic chorus over the latter section. Through the combination of studio effects and overdubs, his vocal performance on the song consists of three contrasting segments; in Inglis' description, these comprise a "naturalistic" approach at the start of the track, "a distorted middle", and chorus singing at the end. To produce the sharp nasal sound over the middle eight, Harrison sang through a filter that limited the signal to a narrow, 3.5-kilohertz band. Described by Everett as "remarkable", the pitch of Harrison's vocals in the final verse ranges from a low E bass note in one of the harmony parts, to a
descant falsetto B4 in the high harmony part. Lennon created a
tape loop of pre-recorded pig noises, sourced from EMI's library, as well as supplying his own grunting sounds. Drum beats were also added, marking the transition from the solo into the third verse. Final overdubs on the song were carried out on 10 October, during the last week of recording for
The Beatles. Having returned from his extended holiday, Martin wrote a string arrangement for four violins, two
violas and two cellos. These parts were recorded during the same orchestral overdubbing session as for Lennon's track "
Glass Onion". Towards the end of "Piggies", Harrison added the spoken words "One more time", before the orchestra played the last two chords. In his overview of the recording, author and critic
Tim Riley interprets the "thick
scouse" delivery of this introduction to the "final grand cadence" as Harrison "smearing social elitists with their own symbols of 'high' culture". Everett refers to the contrast between the various classical elements and the combination of pig sounds and "rude" final cadence as representing an "Orwellian comparison of pigs to socially horrid, though outwardly refined, tyrants".
Mixing on "Piggies" was completed on 11 October. The
mono mix has the animal sounds appearing at different points in the song, relative to the
stereo version. In addition, Harrison's guitar is more prominent in the mono mix. ==Release and reception==
