Ca trù singing

According to UNESCO, Ca trù is a complex form of sung poetry in northern Vietnam, using lyrics written in traditional poetic forms. A Ca trù group consists of three people: the ca nương sings using breath control and nảy hạt vocal ornamentation to create a distinctive timbre while beating the phách clappers; the kép đàn plays the three-stringed đàn đáy with a low tone; and the trống chầu drummer. Some Ca trù performances also include dance.
