Different Thaats of Indian Classical Music

Here's the ChucK file of different Thaats (scales, though not in the most exhaustive sense) of North Indian (Hindustani) Classical Music.

The file has three different functions, the Thaat function which has a sinusoidal wave playing the different thaats, a Tanpura function which serves as the drone and a Taal function, for beat. Also, at different points whenever Thaat changes, its name is printed on the Console Monitor.

Here's the soundcloud link.

Thaat is the base scale of a set of scales dependent on the particular Thaat. While North Indian Hindustani Classical Music has 10 different Thaats, South Indian Carnatic Classical Music has 72!

The different Thaats are:

1. Bilawal: Comparable to the western Ionian mode
2. Kalyan: Comparable to the western Lydian mode
3. Khamaj: Comparable to the western Mixolydian mode
4. Bhairav
5. Purvi
6. Marwa
7. Bhairavi: Comparable to the western Phrygian mode
8. Asavari: Comparable to the western Aeolian mode
9. Kafi: Comparable to the western Dorian mode
10. Todi

Different Ragas are subset of these Thaats. Some Ragas may be belong to two of the thaats. Therefore, it is not a very good way of classifying the Ragas, but, that's how it is.
