The quote 'Just keep swimming' became a global mantra of perseverance in 'Finding Nemo.' Composer Thomas Newman used the marimba to create the 'bubbling' and curious atmosphere of the Great Barrier Reef. The marimba's wooden bars produce a warm, liquid-like sound when struck with soft mallets. Newman’s signature style involves using the marimba in 'minimalist' patterns, providing a sense of constant, gentle motion. This choice helped define the playful yet fragile nature of the ocean, supporting the film's dialogue about family, bravery, and the vast unknown. It remains a legendary example of using percussion to create a 'wet' and immersive cinematic environment.
