Formation of Thaats-Indian Music Theory:
different thaats have been explained below-music formats
We will describe how the thaats formation is made. First of all we will describe
the formation of first thaat, that is “Shuud Thaat”. Well! this is perhaps the most simple formation, the notes used in this thaat are all white keys are used in this thaat, that is (C-E-E-F-G-A-B) or in indian music (Saa- Raay-Gaa-Maa-Paa-Dhaa-Nee)
Now -a-days it is called “Balawal Thaat”. In no other formation all white keys will be used, it is also known as “Kharaag Garaam” because we started from note “C” and this note is called Kharraj in Indian music. If we play the Arohi Amrohi of this thaat, it will be C-D-E-F-G-A-B in either direction.
Now let us start our octave from “D” rather than “C”, so if you play the full seven notes our “D” note will play on “E” note of our first formation that has been described earlier. As a result two notes will change from white to black notes, that is “E” and “B” notes will become black, to play the exact tone of (Do-Re-He-Fa-So-La-Te-De).
This thaat will be called “Kaafi Thaat” in Indian music.
Now let us move to our third formation. Now start your “C” note from “E” note and play all seven notes, as a result all notes will become black notes, it is also called “Bharween Thaat”.
Now our fourth formation will start from “F” note that means considering “F” note as our “C” note we will play all seven notes and it will become “Kalyaan Thaat”.
Now repeating the drill and making “G” as our “C” note and playing all seven notes from there, it will be called “Khamaach Thaat” In our next exercise we will make “A” as our “C” note and similarly play seven notes so as a result we will get “Asawari Thaat”. Now exercise will start from “B” note considering as “C” note and this will be our last last Thaat known as “Todi Thaat”.
