The museum's collections prides itself on the stringed instruments, especially violins (16th-20th c.), including a violin by Marcin Groblicz and by Dankwart, as well as instruments by Italian masters (Amati, Testore, Guadagnini, Maggini). The Chopin Salon exhibits the composer’s memorabilia realted to his stay in Wielkopolska, including the grand piano he used during concerts in Antonin (South Wielkopolska).
