Editing Lucy in the Sky with Diamonds (section)

==Composition==
Most of "Lucy in the Sky with Diamonds" is in [[simple triple metre]] ({{music|time|3|4}} time), but the [[refrain|chorus]] is in {{music|time|4|4}} time. In the song, the structure modulates between [[key (music)|musical keys]], using the key of [[A major]] for verses, [[B-flat major]] for the pre-chorus, and [[G major]] for the chorus.{{sfn|Hal Leonard|1993|pp=646–650}} It is sung by Lennon over an increasingly complicated underlying arrangement which features a [[Tanpura|tambura]], played by [[George Harrison]]; lead electric guitar put through a [[Leslie speaker]], played by Harrison; and a [[counter melody]] on [[Lowrey organ]] played by McCartney and taped with a special organ stop sounding "not unlike a [[Celesta|celeste]]".{{sfn|Lewisohn|1988|pp=100–101}}{{sfn|Ryan|Kehew|2006}} Session tapes from the initial 1 March 1967 recording of this song reveal Lennon originally sang the line "[[Cellophane]] flowers of yellow and green" as a broken phrase, but McCartney suggested that he sing it more fluidly to improve the song.{{sfn|Lewisohn|1988|p=100}}
