Nothing seals the concept of seeing the world entirely through the eyes of children (and a certain man’s best friend) like completely obscuring adult voices. In Charles Schulz’s beloved long-running comic, grownups were neither seen nor heard. Instead the unseen parents and teachers were represented with only a series of wah wahs — the blurred droning of lecturing adults. The iconic rhetoric made its on-screen debut in the 1960s when the TV specials of Schulz’s Peanuts made their first appearances. It was composer Vince Guaraldi (who wrote most of the recognized Peanuts music) who first suggested the use of a trombone to embody the unintelligible speak, which effortlessly reveals the communication gap between children and adults — all without using a single word.
