"Bridge over Troubled Water" is a song by the American folk duo Simon & Garfunkel, released in January 1970 as the second single from their fifth studio album, Bridge over Troubled Water (1970). It was composed by Paul Simon and produced by Simon & Garfunkel and Roy Halee.
"Bridge over Troubled Water" features lead vocals by Art Garfunkel and a piano accompaniment influenced by gospel music, with a "Wall of Sound"-style production. It was the last song recorded for the album, but the first completed.
The instrumentation, provided by the Wrecking Crew, was recorded in California, while Simon and Garfunkel's vocals were recorded in New York. Simon felt Garfunkel should sing solo, an invitation Garfunkel initially declined. Session musician Larry Knechtel performs piano, with Joe Osborn playing bass guitar and Hal Blaine on drums.
The song won five awards at the 13th Annual Grammy Awards in 1971, including Grammy Award for Record of the Year and Song of the Year. It is Simon & Garfunkel's most successful single, and it is often considered their signature song; it topped the US Billboard Hot 100 chart for six weeks, and also reached number one in the United Kingdom, Canada, France and New Zealand.
It reached the top five in eight other countries, eventually selling over six million copies worldwide. It became one of the most performed songs of the 20th century, covered by over 50 artists, including Elvis Presley, Aretha Franklin and Johnny Cash.
It is ranked number 66 on Rolling Stone's 500 Greatest Songs of All Time.
