Nati (dance)
The word Nati is used for the traditional folk dance in the Western and Central Hills of the Indian subcontinent. It  is primarily native to the states of Himachal Pradesh and Uttarakhand. Nati  is traditionally performed in the  Kullu, Mandi,  Shimla, Sirmaur, Chamba, Kinnaur, Uttarkashi, Dehradun (Jaunsar-Bawar) and Tehri Garhwal districts. However, due to high immigration of ethnic paharis in the plains, this has been made popular in the plains too. Traditionally, locals dance to the beats of percussion instruments called Dhol-Damau. Pahari dance is listed in the Guinness Book of World Records as largest folk dance.

Varieties
There are several varieties of Nati performed like  Kullvi Nati, Mahasuvi Nati, Sirmauri Nati, Kinnauri Nati, Jaunpuri Nati, Barada Nati, Bangani Nati. In Garhwali it is also sometimes called Tandi, specially in Tehri Garhwal, and Barada Nati in Jaunsar-Bawar. People of Lahaul district have their own distinct dance called "Garphi" and Nati is not a part of Lahauli culture. The Kinnauri Nati dance is mime-like and includes languid sequences.
