This is not unlike what happens in "Money", a minor-key blues-based song from The Dark Side of the Moon, in which a saxophone solos over the song's predominant 7/4 tempo before switching to a faster 4/4 tempo for the guitar solo. "The Dogs of War" also imitates "Money" in its ending sequence, with a "call and response" between Gilmour's voice and his guitar.
