Travelling musicians and shamans called manaschi are popular for their singing and komuz-playing. Their music is typically heroic epics, such as the most famous story, the Manas epic (20 times longer than Homer's Odyssey), which is the patriotic tale of a warrior named Manas, and his descendants, who fight with the Chinese.
