"Yes It Is" is a song by the English rock band the Beatles. Written by John Lennon (credited to Lennon–McCartney), it was first released in 1965 as the B-side to "Ticket to Ride". It features some of the Beatles' most complex and dissonant three-part vocal harmonies and showcases George Harrison's early use of volume pedal guitar. Ian MacDonald describes the song as having "rich and unusual harmonic motion." Composition In his 1980 interview with Playboy, John Lennon described "Yes It Is" as an attempt to rewrite "This Boy" (the style of the song) that "didn't quite work". Paul McCartney on the other hand described it as "a very fine song of John's" that he and Lennon had finished writing together. Musical structure The song is in the 12/8 time signature, in the key of E and begins (on "If you wear red tonight ...") with a I–IV–ii7–V7 chord progression (E–A–F#m7–B7) in which the word "tonight" (B melody note) appears as a "delicately haunting" 4th above the F#m7, creating a suspension. The melodic pitches of this first two bar phrase are repeated (with initial repetition of the G# melody note) on "remember what I said tonight," except that the B melody note on the second "tonight" is now backed by a ♭VII (D) chord that shapes the B melody note into a more "luscious" 6th. The chorus ("Yes it is, it's true. Yes it is, it's true") involves a I (E chord) – III (G# chord) – IV (A chord) – I (E chord) progression in which the major III (G#) chord appears for the first time in the song to propel the Plagal drop from IV (A) to the tonic I (E) chord. Recording Over the course of a five-hour recording session, the Beatles attempted 14 takes of the basic track before perfecting it. "Yes It Is" was recorded on 16 February 1965, the same day that they completed Harrison's "I Need You". After completing the rhythm track, Lennon, McCartney and Harrison recorded their vocal harmonies in three hours, singing live together using the suggestion of George Martin that they sing their three part harmony in the style of a barber shop quartet. Release and reception "Yes It Is" was released as the B-side of the "Ticket to Ride" single in both the US and the UK. American pressings of the single erroneously show "Yes It Is" as being from
