"Stairway to Heaven" is a landmark progressive rock song by Led Zeppelin, famous for its unique structure and gradual dynamic build-up. It is essentially a multi-part suite that eschews a conventional verse-chorus form. The piece is primarily in A minor and 4/4 time, though it famously includes a transitional section with mixed meters (like 3/4 and 5/4) leading into the guitar solo.
The song begins at a slow tempo (~76 BPM) with a gentle, pastoral feel, characterized by a fingerpicked acoustic guitar duet and mellow recorders. It progressively introduces new layers of instrumentation—John Paul Jones's electric piano and bass, followed by John Bonham's drums—as it builds in intensity. This crescendo culminates in Jimmy Page's iconic, soaring electric guitar solo and a final, powerful hard rock section where Robert Plant's vocals reach an anthemic peak. This epic journey from folk mysticism to a full-blown rock anthem is the song's defining characteristic.
