For about a century, the German harmonica or mouth organ was one of the
most popular musical instruments in the United States. About one billion
harmonicas were imported from Germany between the 1870s and 1980s.
Cheap and portable, it was the pocket-sized companion of European
immigrants, and—once introduced to the American South—it became the
instrument of choice for many African-American musicians. They developed
a totally new way of playing it, ‘bending’ the harmonica’s notes to fit
their traditional musical scale, and making the little instrument an
integral part of the emerging and increasingly popular ‘blues.’
