This is a German-made Hohner Marine Band harmonica, 14-hole, in the key of C. If you can play a general tremolo harmonica, you can play this with a little practice. It has a beautiful and powerful sound from low to high notes, a charming tone that cannot be experienced with other companies' products. Hohner is arguably the oldest and largest keyboard instrument manufacturer in the world, similar to Yamaha and Tombo in Japan. The Marine Band was released as a 100th-anniversary model from 1896 to 1996. It has been used by musicians and in Western movies around the world. Its representative harmonicas are the Blues Harp, Marine Band, and chromatic harmonica, which are particularly famous.
