Tarzan was created by author Edgar Rice Burroughs and first appeared in 1912. The character later became a major figure in films, radio, television, and animation. A distinctive ululating yell became strongly associated with screen portrayals of Tarzan, particularly the Johnny Weissmuller films that began in the 1930s. Many performers and productions have used their own variations, so the precise recording source of this clip is unclear. Online, the call remains recognizable shorthand for jungle adventure, vine swinging, reckless bravery, and exaggerated heroism.
