Sketches still present in the Bagatti Valsecchi archives show the intent to fit the upright piano (whose mechanism, of the French type, was constructed in the second half of the 19th century) into a case that integrated with the carving on the late 16th century wood panelling. Probably purchased by the brothers Fausto and Giuseppe at the end of the 19th century, the piano--an important feature in every upper class home of the day--is still displayed--as are all other objects in the museum--in its original place, thus contributing to the authentic "time capsule" ambiance.
