The Museum of Musical instruments, established in the late 1800s, boasts a collection of several thousand pieces, of which 1,500 are on display. They range from the absurd and inconsequential to the rare and historically crucial. The permanent exhibit is spread over several floors, each with its own theme: the 1st floor is a timeline-style survey; the 2nd floor is analytically organized, tracing the evolution of particular instrumental technologies; the ground floor is dedicated to folk instruments from Europe and around the world; and the basement houses mechanical and 20th century instruments. Visitors wear special headphones that play recordings when triggered by infrared light from individual displays.
In addition to the collections, the museum features a 200-seat concert hall where many of the instruments from the collection are put to use; a restoration workshop where instruments are preserved and repaired in anticipation of use or display; a gift shop; and a restaurant.
