This sound museum is set up in the old Buurkerk church hall and has a magnificent collection of mechanical music instruments from the 18C to the 20C. There you will see old metronomes, music boxes (some with automata), pianolas and \"orchestrions\" (an organ imitating the instruments in an orchestra) intended for cafés and dance halls, including a mechanical Steinway piano (1926) and the automatic violin by Hupfeld (1910).
