Taught by masters to choirs of disciples, Grand Songs are performed formally in the drum-tower, the landmark venue for rituals, entertainment and meetings in a Dong village, or more spontaneously in homes or public places. They constitute a Dong encyclopaedia, narrating the people's history, extolling their belief in the unity of humans and nature, preserving scientific knowledge, expressing feelings of romantic love, and promoting moral values such as respect for one's elders and neighbours. Grand Song is performed widely today, with each village boasting various choirs divided by age and sometimes gender. In addition to disseminating their lifestyle and wisdom, it remains a crucial symbol of Dong ethnic identity and cultural heritage.
