“Baby’s in Black” is a song by the Beatles, co-written by John Lennon and Paul McCartney. The song appears on the United Kingdom album Beatles for Sale and in North America on Beatles ’65.
“Baby’s in Black” is performed at a 6/8 time signature with a moderate tempo that makes it sound like 3/4 (waltz-time). AMG described the song as “a love lament for a grieving girl that was perhaps more morose than any previous Beatles’ song.” Musicologist Alan W. Pollack notes that the song is relatively complex in format, with a refrain, bridge, and a guitar solo. He describes the song as having “mishmash” of stylistic elements—among them, “bluesy” chords and country music-inspired vocals.
They performed “Baby’s in Black” live during their appearances from late 1964 until their last tour in 1966. McCartney said they introduced the song by saying, “‘And now for something different.’ … We used to put that in there, and think, ‘Well, they won’t know quite what to make of this, but it’s cool.'” In 1996, a live version of “Baby’s in Black” was released as a B-side to “Real Love”, the second single from their Anthology project.
