German Harmonica and Accordion Museum Reopens After Refurbishment

The German Harmonica and Accordion Museum has recently been reopened. Nearly 25,000 different Harmonicas from all over the world are represented in all aspects and variations, many having a high cultural and historic value. The ingenuity and adaption of current trends which created models like the ‘Zeppelin’ and ‘Banana’ Harmonica are displayed in a modern well designed setting and are lovingly preserved by curator Martin Huffier and make up the largest single collection in the world

There is also a huge permanent display of some 500 square metres with a large variety of Piano and Diatonic Accordions, as well as the history of these fabulous instruments. You can see the construction of the instruments and the history of their cultural development. The museum tour ends with an attractive multi-media room where movies, documentaries and lectures are also given.

It is a fascinating visit where you will find the story of Matthias HOHNER, his rise to fortune and the assimilation of his numerous competitors. The museum in Bau V, was the former factory building on the original HOHNER factory site.

  • The picture with Ernst Hohner can’t date back to 1920!!!
    There are many accordion models on shelves looking in 1950s fashion … even a button Morino.
