The Galo tribe, native to Arunachal Pradesh, shares a close bond with nature and spirituality. They are best recognized for their colorful Mopin festival, where they conduct the Popir dance as an offering to Mopin Ane in order to receive blessings for prosperity and safety. Their culture is a mix of worship and celebration, with high levels of community participation. The Galo people worship Donyi Polo (Sun-Moon) as a central deity and practice special traditions that have been nurtured over generations and represent their sacredness for nature and their common heritage.

The Popir Dance is set to the rhythmic sounds of the Yoksha, a unique, sword-shaped instrument with iron discs that produce a rattle. Played by the Miri, a male singer, the Yoksha accompanies folk songs narrating Galo origin tales. This musical backdrop harmonizes with the dancers’ movements, creating a festive yet reverent atmosphere. The music, both lively and melodic, encapsulates Galo traditions, reflecting their respect for Donyi Polo and enhancing the festival’s communal spirit and joyous expression.
