"Cecilia" is a song by American folk rock duo, singer-songwriter Paul Simon and singer Art Garfunkel. The song was released in April 1970 as the third single from the group's fifth studio album, "Bridge over Troubled Water" (1970). The song was written by Paul Simon. the song's origins lie in a late-night party. They got the rhythm when the duo and friends began slapping their thighs and drumming on a piano bench. They recorded the sound with a tape recorder, employing reverb and matching the rhythm created by the machine. Simon later wrote the song's guitar line and lyrics on the subject of an untrustworthy lover. Simon didn't remember what inspired him but he remembered Cecilia was the goddess of music.
