Led Zeppelin's iconic song "Stairway to Heaven" was released in 1971. It begins with an acoustic guitar introduction that sets a mysterious mood. Throughout the song, layers of instrumentation are gradually added, such as electric guitar and drums, building intensity. Jimmy Page's guitar solo modulates between scales. The lyrics leave room for spiritual and mystical interpretation. Over time, the song's texture and dynamics evolve from a sparse introduction to a full band crescendo.
