The origin of Polish music can be traced as far back as the 13th century, from which manuscripts have been found in Stary Sącz, containing polyphonic compositions related to the Parisian Notre Dame School. Other early compositions, such as the melody of "Bogurodzica", may also date back to this period. The first known notable composer, however, Mikołaj z Radomia, lived in the 15th century. The melody of "Bóg się rodzi" by an unknown composer was a coronation polonaise for Polish kings.
