Quan họ is a traditional form of folk music originating from the northern regions of Vietnam. It is characterized by its unique call-and-response singing style, often performed by groups of singers, typically women and men. The songs express themes of love, nature, and daily life, and are usually accompanied by traditional instruments. This musical genre is often performed during festivals and cultural events, showcasing the rich heritage of the Kinh people. In 2009, quan họ was recognized by UNESCO as an Intangible Cultural Heritage of Humanity, highlighting its significance in preserving Vietnamese culture and traditions.
