“The Sound of Silence” by Simon & Garfunkel was witten in February 1964 by Paul Simon in the aftermath of the 1963 assassination of John F. Kennedy. It was originally recorded as an acoustic piece for their first album Wednesday Morning, 3 A.M. in 1964 but on the initiative of the record company’s producer, Tom Wilson, it was later overdubbed with drums, electric bass and electric guitar, all without the knowledge or participation of Simon & Garfunkel and rereleased as a single in September 1965.
“The Sound of Silence” was originally called “The Sounds of Silence” and is titled that way on the early albums in which it appeared and on the first single release; only on later compilations was it retitled “The Sound of Silence”. Both the singular and the plural appear in the lyrics. In his book Lyrics 1964–2008, Simon has the title in the singular.
