Mathias Hohner started making harmonicas in his kitchen in Trossingen, Germany. Amazingly, Hohner harmonicas are still made at a factory in Trossingen, Germany after all these years. I don’t think there’s any question that the Hohner Harmonica has had a profound influence on American music. The harmonica is one of the easiest and most fun instruments I have ever learned how to play. I play the awesome Hohner Blues Harp harmonica.
