In working on the album, Waters decided to create three parts of a song that would become "Another Brick in the Wall." Sharing the basic melody and refrain, the three parts came at different points in the story, all bringing the main character (named Pink) to isolate himself from other people. Originally, all three parts were meant to be relatively brief, with one verse and one chorus each. Parts 1 (about the death of his father) and 3 (about drugs and the end of a relationship) kept to that idea, but Part 2 ended up a little different. The middle composition, dealing with an imaginary children's revolt against abusive schoolmasters, grew in stature during the recording process.
