The concertina has historically been a favorite instrument among people who travel often (due to its small and compact size), leading it to be a common instrument among soldiers, sailors, and cowboys. One was even brought aboard Robert Peary’s 1891 expedition of the Greenland Arctic. Despite the pop-culture association of the concertina with the Golden Age of Piracy, the concertina was invented approximately 100 years after the heyday of piracy in the North Atlantic.
