One of Gilmour's ideas for the solo section was that, for the second chorus of the solo, all special effects would be completely off (referred to as "dry"), creating the sense of just four musicians playing in a small room. For this "dry" chorus, all musicians played softly and subtly, with Gilmour's solo, now one single guitar, playing very little. Then, for the third chorus, the dynamics would suddenly rise, with heavy use of reverb and echo (a "wet" sound), additional rhythm-guitar parts in the background, and the drums becoming heavy and almost chaotic.
