In poetry, a tetrameter is a line of four metrical feet. However, the particular foot can vary, as follows:
 * Anapestic tetrameter:
 * "And the sheen of their spears was like stars on the sea" (Lord Byron, "The Destruction of Sennacherib")
 * "Twas the night before Christmas when all through the house" ("A Visit from St. Nicholas")
 * "And since birth I've been cursed with this curse to just curse / And just blurt this berserk and bizarre s**t that works" (Eminem, "The Way I Am")
 * Iambic tetrameter:
 * "Because I could not stop for Death" (Emily Dickinson, eponymous lyric)
 * Trochaic tetrameter:
 * "Peter, Peter, pumpkin-eater" (English nursery rhyme)
 * Dactylic tetrameter:
 * Picture your self in a boat on a river with [...] (The Beatles, "Lucy in the Sky with Diamonds")
 * Spondaic tetrameter:
 * Long sounds move slow
 * Pyrrhic tetrameter (with spondees ["white breast" and "dim sea"]):
 * And the white breast of the dim sea
 * Amphibracic tetrameter:
 * And, speaking of birds, there's the Russian Palooski, / Whose headski is redski and belly is blueski. (Dr. Seuss)
