Musical instruments in the custody of the National Museum in Poznań are housed by its two departments: the Musical Instrument Museum and the Ethnographic Museum. The former (established after World War II and endowed with Zdzisław Szulc's pre-war collection) boasts around 2500 exhibits from all continents: European professional and folk instruments, non-European instruments, and musical documents, from the past and the present, the oldest dating back to the Lusatian and pre-Columbian cultures. The museum has a particularly impressive collection of plucked and bowed string instruments, keyboard instruments, wind instruments, and Polish folk instruments. The Ethnographic Museum's post-war collection contains instruments mainly from the region of Greater Poland (Wielkopolska), dating from the 19th and the 20th century.
