Japanese tremolo tuning In Europe and the United States, tremolo harmonica uses the Richter tuning, developed in Germany. In 1913, Shōgo Kawaguchi (), known in Japan as the "Father of the harmonica", devised an alternate tuning, which is more suited to playing Japanese folk tunes. This tuning is also suited to local music throughout East Asia, and harmonicas using the tuning became popular in the region.
