"Stairway to Heaven" is a song by the English rock band Led Zeppelin, released in late 1971. It was composed by the band's guitarist Jimmy Page and vocalist Robert Plant for their untitled fourth studio album (often called Led Zeppelin IV). The song is sometimes regarded as the most popular rock tune of all time. The song has three sections, each one progressively increasing in tempo and volume. The song begins in a slow tempo with acoustic instruments (guitar and recorders) before introducing electric instruments. The final section is an uptempo hard rock arrangement highlighted by Page's intricate guitar solo (considered by many to be one of the greatest ever) accompanying Plant's vocals that end with the plaintive a cappella line: "And she's buying a stairway to heaven."
