"Stairway to Heaven" is described as progressive rock,^[17][18] folk rock^[19] and hard rock.^[19] The song consists of three distinct sections, beginning with a quiet introduction on a finger-picked, six-string acoustic guitar and four recorders in a Renaissance music style^[20] (ending at 2:15) and gradually moving into a slow electric middle section (2:16–5:33), then a long guitar solo (5:34–6:44), before the faster hard rock final section (6:45–7:45), ending with a short vocals-only epilogue. Plant sings the opening, middle and epilogue sections in his mid vocal range, but sings the hard rock section in his higher range which borders on falsetto.
