12.What is Razakhani gat and how does it differ from the Masitkhani gat?

What is Razakhani gat and how does it differ from the Masitkhani gat? Is it due to the a) tempo b) bol patterns or c) uthan from a particular matra? Or are all these factors designed in a particular manner?

a. Masitkhani gats are played in slow or vilambit laya while the Razakhani gats are played in drut or fast laya.
b. Bol patterns are distinctly different. While Masitkhani gats have a clear distinct bol pattern, the Razakhani gats also have fixed pattern with a slight flexibility. Both gats are played only in Teentaal. The bols start from 12th matra. Razakhani gats also have a prescribed bol pattern which is also fixed but slight variations permitted according to the melodic mould of the related gat.
c. As mentioned, Masitkhani gats start from 12th matra. Also, as mentioned the Razakhani gats could start from the sam or khali or even the 7th matra of Teentaal. Both the gats are played only in Teentaal, though one of our past students had found some Masitkhani gats in Ektaal as well during her research on sitar.
