It is basically a mechanical music (street organs, dance organs and musical boxes), museum. There are however, quirky and humourous automata. The staff are happy to demonstrate the exhibits to show that they are not just prettied up superficially but actually work. They are a tribute to the restorers craft and even though most are knocking on for a century old and some are much older (the instruments that is, not the restorers), they work and sound as if they were new.
As an example of the eye for detail and sympathy for the design of the building, (it is a functioning church), all the exhibits are in soundproof rooms around the edge of the inside space. You are taken through the rooms starting with the quiet instruments, music boxes and the like and finishing with the big organs that rattle the eardrums. As someone who used to own a Dutch street organ, I know what goes on round the back, but anyone who didn`t and was fascinated, had only to ask.
The guides are very talented people. Mostly young, they have no problems with giving the talks in two or more languages. They are friendly, warm and so badly want you to ask questions. In fact, you feel a bit of a swine if you don`t, because they really want to inform you. If you are ambivalent about mechanical music, go anyway - You`ll enjoy it. The tour, depending on questions asked, takes about an hour.
