Ummatt-aat, a folk dance performed by Kodava women, is performed in which region?

The correct answer is Coorg (Karnataka). Ummatt-aat (also written Ummathat) is a traditional folk dance of the Kodava community of Kodagu (Coorg), a hilly district in the southern part of Karnataka, known for its coffee plantations, forests and the source of the river Kaveri. The Kodavas are a distinct community with their own language (Kodava Takk), customs, dress and martial traditions.

Ummatt-aat is performed by Kodava women. The dancers wear the traditional Kodava saree, which is worn in a distinctive style, with the pleats at the back, along with traditional jewellery and a headscarf. They hold brass cymbals in their hands and dance in a circle, with graceful, rhythmic movements, clapping the cymbals in time with the songs. The dance is usually performed in honour of the goddess Kaveri, the river goddess who is the presiding deity of the Kodavas, and at weddings and festivals. One of the most important festivals of Kodagu is Kaveri Sankramana, held in October, when the river Kaveri is believed to appear as a sudden gush of water at Talakaveri, its source. Another major festival is Huttari, the harvest festival of the Kodavas, held in November or December.

The Kodavas also have dances performed by men, such as Bolak-aat (performed in the open, with a lamp in the centre, holding chavari (yak tail whisks) and daggers) and Kolaata (a stick dance). The Kodavas are known for their martial traditions and are among the few communities in India legally allowed to carry firearms without a licence. Field Marshal K. M. Cariappa and General K. S. Thimayya, two of India's most famous army officers, were Kodavas.
