The sections build with more guitar layers, each complementary to the intro, with the drums entering at 4:18. The extended Jimmy Page guitar solo in the song's final section was played for the recording on a 1959 Fender Telecaster given to him by Jeff Beck (an instrument he used extensively with the Yardbirds) plugged into a Supro amplifier, although in an interview he gave to "Guitar World" magazine, Page also claimed, "It could have been a Marshall, but I can't remember". Three different improvised solos were recorded, with Page agonising about which to keep. Page later revealed, "I did have the first phrase worked out, and then there was the link phrase. I did check them out beforehand before the tape ran." He has likened the song to an orgasm.
