The joint
Holden hears a song in the street and builds a vocation out of a word the song does not use. Burns wrote “if a body meet a body, coming through the rye.” Holden wants “catch.” His little sister corrects him. The title is the mishearing, and the mishearing only matters if the reader can feel the original.
German Der Fänger im Roggen is the straight road: catcher, rye, the role intact. The citation still breaks, because Burns is not a German proverb. The translator’s note, or the scene with Phoebe, has to do the work the title did for an Anglophone reader in 1951.
野崎孝’s ライ麦畑でつかまえて describes the act in a rye field and turns the catcher into a verb. 村上春樹’s later title transliterates the English and leaves the meaning in the foreign words. French L’Attrape-cœurs does a third thing, and it is the bold one: it throws the song away and offers hearts. A reader of that title is not failing to remember Burns. Burns was never invited.
Why this break matters to a reader
The cliff, the children, the catcher: those arrive in the chapter where Holden explains himself, in any decent translation of that chapter. The title is the early, quiet version of the explanation. Where the title keeps the field, the reader walks in already standing in the rye. Where the title says “hearts,” the reader walks in under a different metaphor and only later finds the field. Where the title is katakana, the reader walks in under a sound. All three are readings of the book. They are not the same entrance.
