Slide whistles became a staple of classic American cartoon sound design, and this clip comes from the Hollywood Edge library under a collection of ascending and descending whistles. The existing notes credit Disney sound artist Jimmy MacDonald and the Donald Duck cartoon Grand Canyonscope, released on 23 December 1954. Short whistle glissandos like this survived the move from theatrical shorts to television, games and online edits because they communicate motion instantly. Editors still reach for the rise and fall version when a single up down movement needs a clear, old school cartoon accent.
