Thaats

A thaat  is a "Parent scale" in North Indian or Hindustani music.^[1][2] The concept of the thaat is not exactly equivalent to the western musical scale because the primary function of a thaat is not as a tool for music composition, but rather as a basis for classification of ragas.^[2] There isn't necessarily strict compliance between a raga and its parent thaat; a raga said to 'belong' to a certain thaat need not allow all the notes of the thaat, and might allow other notes. Thaats are generally accepted to be heptatonic by definition.
The term thaat is also used to refer to the frets of stringed instruments like the sitar and the veena.^[3] It is also used to denote the posture adopted by a Kathak dancer at the beginning of his or her performance.
