"In the Light" is a song by English rock band Led Zeppelin from their 1975 album Physical Graffiti.
The song was composed primarily by bassist/keyboardist John Paul Jones on synthesiser, though singer Robert Plant and guitarist Jimmy Page also received songwriting credits.
The unique sound of the intro was created by Page using a bow on an acoustic guitar, as a backdrop to Jones' opening synthesiser solo.
"[7] Miller continues "the problem here is not tedium but a fragmentary composition that never quite jells: When Page on the final release plays an ascending run intended to sound majestic, the effect is more stilted than stately.
"[8] In an interview he gave to rock journalist Cameron Crowe, Plant stated that this song was one of Led Zeppelin's "finest moments".
