The song is the first of many Pink Floyd songs to prominently feature an E minor added ninth chord. This chord would become a signature aspect of their better-known material: It opens "The Dark Side of the Moon" with "Breathe". It is prominent in "Welcome to the Machine" from "Wish You Were Here", where it alternates with a C Major seventh chord for most of the song. "Dogs" from "Animals" centers around the chord as played on down-tuned guitars, resulting in a concert pitch of D minor ninth. It appeared again in "Hey You" and "Vera" from "The Wall". It would appear in no less than four songs from "The Final Cut": "Your Possible Pasts"; "The Hero's Return"; "The Gunner's Dream"; and "The Fletcher Memorial Home".
