"Silver Swan" can refer to a brand of Filipino food products, a 18th-century automaton, or a 16th-century madrigal, so its description depends on context. The food brand produces soy sauce, oyster sauce, and other condiments, while the automaton is a clockwork musical device featuring a life-sized, preening swan that "eats" a fish. The madrigal is a musical piece that uses the legend of the swan singing a mournful song at death as a metaphor.
