- A Thaat is a sequential set of seven out of 12 notes.

Trick to easily remember the 10 Thaats.
Memorize this sentence – “Bhigi Kal Khoob Barish Me Kya Pata Aye Bukhar Tujhe”
Each of the first letter of the above words, represents the first letter of the following Thaats. E.g., Bhigi=Bilawal; Kal=Kalyan; Khoob=Khamaj; Barish=Bhairav; Me=Marwa; Kya=Kafi; Pata=Poorvi; Aye=Asavari; Bukhar=Bhairavi and, Tujhe=Todi.
Now memorize a phone number – 0112223344
These numbers represents the number of vikrit swars that these 10 Thaats contain. E.g., 0=Bilawal as it has got no vikrit swar. 1,1 are the next two Thaats – Kalyan and Khamaj that contain one vikrit swar each. Then 2,2,2 are the next three Thaats – Bhairav, Marwa and Kafi, that contain two vikrit swars each. Then 3,3, are the next two Thaats – Poorvi and Asavari, that contain three vikrit swars each. And lastly, 4,4, are the final two Thaats – Bhairavi and Todi, that contain four vikrit swars each.
