Shanties are the work songs that were used on the square-rigged ships during the "Age of Sail." Their rhythms coordinated the efforts of many sailors hailing on the lines (ropes).
This song actually did double duty, serving not only as a drinking song, but as music by which the sailors would dance, their steps being easily recognizable as those one would execute while atop in the rigging.
This is one movement from a suite of four well-known, traditional sea shanties, a choice if only a single movement is desired. See Abernathy – Sea Shanties for the complete suite at a discounted price.
