Xoan singing (also called hat cua dinh, lai len singing, dum singing, tho singing…) is a kind of performing art, attached to cult of worshipping Hung Kings and performed by farmers growing wet rice in the midland areas, mainly in Phu Tho Province.
Xoan singing was originated in several localities in Phu Tho Province, including guilds of Phu Duc, Kim Doi, Thet (Kim Duc Commune) and An Thai (Phuong Lau Commune), Viet Tri City. There are three forms of Xoan singing as the worship singing to commemorate Hung Kings and village guardian gods; the ritual singing to pray for good crops, good health; and the festive singing – a form of love duet.
Often practiced in spring, Xoan singing is a combination of poetry, music, singing, dancing. There exists tight attachment between poem and rhythm, the meaning of poem unites with music. Xoan singing has three types: recital melody (hat noi); chanting melody (hat ngam ngoi) and praising melody (hat xuong).
