The poem "The Song of Hiawatha" by Henry Wadsworth Longfellow showcases many good examples of trochaic meter. A trochee is a metrical foot consisting of a stressed syllable followed by an unstressed syllable, as in the word "double."
Here is one example from Longfellow's poem: "Aim your arrows, Hiawatha, / At the head of Megissogwon." Notice how the words here have a stressed-unstressed rhythm that adds a powerful forward momentum to the language. William Shakespeare also used trochaic meter, especially when he wanted to signal spells and incantations, as in the famous spell of the three witches in "Macbeth": "Double, double, toil and trouble; / Fire burn and cauldron bubble."
