The film is bookended with surrealist sequences centred around Merrick's mother and her death. Lynch used Samuel Barber's Adagio for Strings to underline the climax and Merrick's own death. Composer John Morris argued against using the music, stating that "this piece is going to be used over and over and over again in the future... And every time it's used in a film it's going to diminish the effect of the scene."
