ballad with a pop element made explicit through the intro, instrumental passage and coda. The chords used in the introduction (E throughout) and chorus (B, F, E and E7) suggest a key of B major. In musicologist Walter Everett's description, however, the B chord "reveals itself to be the V of V of A" once the verse is heard for the first time. The key change to D major occurs midway through the second verse, for the piano solo. The six-bar choruses depart from the standard 4/4 time signature by including bars in 3/4 and 5/4 time. Music critic Ian MacDonald describes the chorus as a section that "drop[s] beats left, right, and centre" in contrast to the "barrelhouse 4/4" of the verse. In his analysis of the song, Pollack says that while he had long considered the chorus's metre to vary in this way, the effect is more one of syncopation within 4/4, rather than formal changes in time signature. Within the three two-bar pairings, he continues, this is achieved through rhythmic accents falling on beats 1 and 4 of the first bar and beat 3 of the second bar. Like the Revolver track "She Said She Said", the song closes with an imitative canon in the voices. Author Mark Prendergast likens the ending to that of "I Want to Tell You", saying that where the latter closes with an uplifting Indian devotional quality, "Good Day Sunshine" features a "raga-like edge to its vocal climax". The ending is given extra emphasis through the melody ascending a semitone from the final chorus, to an F7 chord. According to author Mark Hertsgaard, the lyrics combine an appreciation of the sun's life-affirming qualities with a "standard boy–girl love story". In focusing on the latter theme, the song serves as a comparative rarity on Revolver, where the Beatles otherwise avoid the subject of love. As with some of his other songs on the album, this trait set McCartney apart from Lennon and Harrison, whose lyrics increasingly addressed existential concerns. Recording The Beatles rehearsed "Good Day Sunshine" extensively in the studio on 8 June 1966, before recording three full takes of the basic track. Take 1 was selected for overdubbing, which they completed the following day. The basic track consisted of piano, bass guitar and drums. MacDonald was unsure if Lennon played guitar. According to Everett, where the Spoonful's "Daydream" includes "a Beatlesque staggering
