"Stairway to Heaven" is a song by the English rock band Led Zeppelin, released in late 1971. It was composed by guitarist Jimmy Page and vocalist Robert Plant for the band's untitled fourth studio album (often referred to as Led Zeppelin IV). It is often referred to as one of the greatest rock songs of all time. The eight minute and two seconds song has three sections each one progressively increasing in tempo and volume. It starts as a slow acoustic-based folk melody accompanied by recorders before introducing electric instrumentation. The final section is an uptempo hard rock arrangement highlighted by Page's intricate guitar solo accompanying Plant's vocals that end with the plaintive a cappella line: "And she's buying a Stairway to Heaven".
