6月20日に本作のためにレノンとオノ、ジョージ・ハリスン、ジョージ・マーティンの4人が集った[注釈 2]。スタジオ3で集めた効果音でテープ・ループを作成し、これを数台のテープ・レコーダーでを再生しながらライブ・ミックスし、曲の5分11秒の辺りでレノンとハリスンの会話を録音して追加した[10]。レノンは「ジョージとオレは20分ほど適当に喋った」「言葉は全て思いつきで、脚本なんてものは存在しなかった」と語っている[10]。また、「レボリューション」のテイク18のコーダ部分に含まれていたオノの「You become naked」という言葉や、ピアノの伴奏の断片も本作に含まれている。
Taylor: bottle of claret for you if I'd realized. I'd forgotten all about it George, I'm sorry... Martin: Well, do next time Taylor: Will you forgive me? Martin: Mmmm...yes... Taylor: Cheeky bitch.[14]

Humanities (National Endowment of the Humanities) 34 (5). http://www.neh.gov/humanities/2013/septemberoctober/statement/beatles-reflection. "The Beatles, by contrast, was scruffy and centerless, its thirty songs encompassing mock-Beach Boys vocal harmonies ('Back in the U.S.S.R.'), ... proto-punk ('Helter Skelter'), sound collage ('Revolution 9'), and plenty more besides."
^“Notes on 'Revolution #9'”. Soundscapes.info. 2021年11月1日閲覧。 “As one of the more infamous achievements of the mid twentieth century avant garde, this form of musical composition challenges the listener on both psychological and philosophical grounds.”
^Unterberger 2006, p. 210. "The other Beatles and George Martin probably would have been happy enough to keep 'Revolution 9' under wraps, but John Lennon was probably determined to get at least one of his avant-garde outings on the record."
^Everett 1999, p. 174. "The six-minute remainder formed the basis of a musique concrète work, largely a Lennon-Ono collaboration 'painting in sound a revolution,' 'Revolution 9'"
^Courrier 2009, p. 226. "Composed as a piece of musique concète by Lennon and Yoko out of various taped pieces, including radio broadcasts, plus outtakes from the outro of 'Revolution 1,' 'Revolution 9' was highly influenced by the pioneers of Dadaist experimentation."
