While in Hanoi we had the opportunity to visit a traditional Vietnamese type of music, it was called Ca Tru. A World Cultural heritage recognized by UNESCO. It involved traditional string instrument with also accompanied by a female singing in this weird kind of guttural voice, similar to operatic singing this was also accompanied by a person playing some kind of wooden sticks and a drum. There was a quite large focus on keeping this art form alive as it had nearly become endangered. It was really pleasant to listen and the sounds drew you further into them. At the end there came on two traditional dancers which accompanied the musicians.
