Near the beginning of the song, Jimmy Page played his guitar with a violin bow. He also used the bow on "Dazed And Confused
" and "How Many More Times
." Talking about the song in the BBC book The Guitar Greats
, Page said: "Once the vocal lines and phrasing were sorted out, you'd know where not to play, which was as important as knowing when you should play. With 'In The Light,' for instance, we knew exactly what its construction was going to be, but nevertheless, I had no idea at the time that John Paul Jones was going to come up with such an amazing synthesizer intro, plus there's all the bowed guitars at the beginning as well, to give the overall drone effect. We did quite a few things with drones on, like 'In The Evening' and all that, but when he did that start for 'In The Light' it was just unbelievable."
