A walk through the museum shows about 250 years of mechanical musical instruments. The smallest of the museum’s objects is a music box: it measures just 1.5 cm × 1.5 cm – which is a difference to the carousel organ measuring 3.00 m × 4.00 m. Almost all instruments are ready to play, and guided tours of the museum give the visitors many different sound experiences. Britta Edelmann, MA – museum director.
