In the 1890s the Band of the US Marines was led by the famous
American composer John Philip Sousa, who was a great advocate of the
harmonica as a tool for popular musical education. Hohner named the

was (and still is) the largest market for their instruments, Hohner
naturally used a lot of English names. They also used Portuguese,
Italian and other languages where it was appropriate for the market
