“The sailor’s songs for capstans and falls are of a peculiar kind, having a chorus at the end of each line. The burden is usually sung, by one alone, and, at the chorus, all hands join in,—and the louder the noise, the better. With us, the chorus seemed almost to raise the decks of the ship, and might be heard at a great distance, ashore. A song is as necessary to sailors as the drum and fife to a soldier. They can’t pull in time, or pull with a will, without it. Many a time, when a thing goes heavy, with one fellow yo-ho-ing, a lively song, like ‘Heave, to the girls!’ ‘Nancy oh!’ ‘Jack Cross-tree,’ etc., has put life and strength into every arm.” – Richard Henry Dana, Two Years Before the Mast
