Researcher Trinh Bach, who is a royal descendant, also restored a loom used to weave silk threads.

In the project, run by the Relics Conservation Centre, profiles on Nha Nhac costumes and orchestral instruments were compiled and more than 1,000 documents written during the Nguyen Dynasty were collected and are now kept in newly established archives.

As part of the project, 20 instrumentalists received formal training in Nha Nhac, while more than 100 practitioners and mentors were trained in art conservation.

Dozens of performances were held both inside and outside the country to promote Nha Nhac.

The successful restoration of Thai Binh Co Nhac, a royal performance of drums, was one of the highlights of the project, according to officials. The project cost USD 350,000, of USD which 155,000 was donated by the Japan’s Trust Fund via UNESCO.
