Pierre Jaillard Bressan was a leading wind instrument maker of his time. Evidence of the success met with his contemporaries can certainly be found in the large number of specimens that have survived, namely, recorders in various sizes, ranging from the soprano recorder to the bass recorder, and transverse flutes. This instrument is a tenor recorder, with maple body, and ivory mouthpiece and rings. Considering its historical value, it is one of the most important items in the museum’s collection, despite the far from excellent conditions. Indeed, it has several cracks resulting from poor maintenance in the past and careless previous repairs. In 1995 the instrument was subjected to careful conservative restoration, during which the silver key that is now present was also reconstructed (the original key was lost): it was moulded along the lines of a key of another tenor recorder made by Bressan and preserved at the Musikinstrumenten Museum in Berlin (Cat. no. 96).
