"Eleanor Rigby" is a song by the Beatles, released on the 1966 album Revolver and as a 45 rpm single. It was written by Paul McCartney, and credited to Lennon–McCartney. "Eleanor Rigby" does not have a standard pop backing. None of the Beatles played instruments on it, though John Lennon and George Harrison did contribute harmony vocals. Like the earlier song "Yesterday", "Eleanor Rigby" employs a classical string ensemble—in this case an octet of studio musicians, comprising four violins, two cellos, and two violas, all performing a score composed by producer George Martin. It is arranged here for flute trio. I have not simply transcribed the string parts, but have added sustaining notes. The melody is carried by flutes 1 & 2 with flute 3 carrying the important bass line.
