Vi-Giam singing is popular in nearly 260 villages in the central provinces of Nghe An and Ha Tinh.
The two provinces have 51 singing clubs with over 800 vocalists, many of whom are actively preserving the folk music.
Vi-Giam folk music, estimated to have 15 tunes of Vi and 8 airs of Giam, is a repartee sung while working. It reflects the work, cultural lives and feelings of the residents in the central coastal provinces.
