Story 
"Because" is a song written by John Lennon and recorded by the English rock band the Beatles. It was released on their 1969 album Abbey Road, immediately preceding the extended medley on side two of the record. It features a prominent three-part vocal harmony by Lennon, Paul McCartney and George Harrison, recorded three times to make nine voices in all. [Wikipedia]
Because is a song by The Beatles, written by Lennon and led on vocal by John Lennon, Paul McCartney & George Harrison. Inspired by Yoko playing 'Moonlight Sonata' backwards; nine-part harmony (3×3 overdubs). Within the catalogue, its harpsichord thread connects it to Fixing a Hole, Piggies. John Lennon's 'Because' emerged as Abbey Road's most technically ambitious orchestral composition, recorded 1 August 1969 as the album's final recording session. The composition's three-part vocal harmony featuring John Lennon, Paul McCartney, and George Harrison created one of the Beatles' rarest vocal configurations. The harmonic sophistication and backward-recording technique (the vocal harmonies were derived from Chopin's Piano Sonata No. 8) established it as the group's most conceptually elaborate piece (Lewisohn 1988, p.154, 171). The song's intellectual approach to composition—building from classical music principles—exemplified the band's artistic maturity and confidence in complex structures. (Kozinn 1995)
The session work falls within the band's Abbey Road (1969) period, recorded 1 Aug 1969 at EMI Studios. George Martin produced; Geoff Emerick (returned), Phil McDonald, Glyn Johns engineered. For session-by-session detail, see Mark Lewisohn's account on p.6 of The Complete Beatles Recording Sessions (excerpt below). The recording required three voices (Lennon, McCartney, Harrison overdubbed to create a six-voice total texture) performing closely-harmonized parts. Engineer Ken Scott oversaw the complex vocal-tracking procedure, capturing precise pitch and timing control. The orchestral accompaniment featured strings and winds, creating the composition's richly textured orchestral foundation. Multiple takes and careful vocal editing ensured harmonic alignment (Lewisohn 1988, p.154). The Moog synthesizer's bass lines provided harmonic foundation while the three Beatles' vocals were carefully layered and blended, showcasing Emerick's vocal production artistry. (Emerick 2006) Because demonstrated Abbey Road's harmonic ambition, its three-part vocal harmony built over a Moog-enhanced Beethoven-derived progression creating cathedral-like chromatic richness.
