1. General Introduction
The Dan Tinh Tau (also known as Tinh Tau or Tinh Buot) is a traditional stringed instrument of the Tay, Nung, and some White Thai communities in Vietnam’s northwest region, including Son La Province. It is not only a musical instrument but also carries spiritual and healing significance in ethnic cultural life.

2. Distinctive Features

- Structure: The Dan Tinh has a long wooden neck with a dragon-head carving, and a gourd-shaped resonator made of hollowed wood. It typically has two or three strings made of silk or metal.

- Sound: Warm, mellow, and deep – the tones are calming and soulful.

- Playing Technique: Played by plucking with the fingers, often accompanying singing, chanting, or ritual incantations, creating a sacred, mystical atmosphere.

3. Cultural and Spiritual Role

- Closely associated with the role of the Tao Master (Thầy Tào) – a spiritual healer and protector of the community. The Dan Tinh is a sacred object, used only during rituals.

- The primary instrument in Then rituals, an essential spiritual ceremony of the Tay people, which was recognized by UNESCO as an Intangible Cultural Heritage of Humanity.

- Outside of rituals, it is used to accompany Then singing, romantic folk songs, and poetic expressions of highland life and emotions.

4. Preservation and Development

- Today, the Dan Tinh is being integrated into ethnic music education, cultural performances, and community tourism programs.

- Many artisans and cultural practitioners in Son La are actively teaching the craft of making and playing the Dan Tinh, ensuring its legacy continues among younger generations.
