Supercalifragilisticexpialidocious

The great technical achievement of "Supercalifragilisticexpialidocious" is that it sounds effortless despite being a delivery challenge of some ambition, Andrews and Dick Van Dyke spinning the impossible word through multiple tempos and contexts without once losing the sense of play. The Cockney setting gives the song its specific texture — music-hall exuberance filtered through Andrews' training, the class-consciousness of the setting serving as ironic frame for a song about language as social currency. The rhythm is intoxicating, the percussion driving forward with the energy of something that knows it's getting away with something. As a piece of pure sound design the title word is a masterstroke, phonetically satisfying regardless of language background. The song captures something true about the way invented words can function as social password — that sounding confident about nonsense is its own form of charm. Andrews understood this perfectly, performing it as genuine conviction rather than winking parody.
