'Vibhag' (in music) represents a duration of rhythmic phrasing in Indian classical music made up of a certain number of beats.
They are the rough equivalent of bars in western music, but instead of always being equal subdivisions of the tala (the rhythmic cycle - think 12 bar blues), they can be uneven.
The talas in Tabla or in any other percussion instrument in classical music have Vibhagas to get a track of the beats on Matras on which the singer or player is singing or playing on.
So Teental with Vibhags is written as This can also be shown using the following figure If you see both the tables then you may realize that after every 4 syllables i.e. considering the 1st line so Dha Dhin Dhin Dha after this is a line like this | .
Those conclusions are that there will be 4 more vibhags after every 4 matra like it was there in the 1st line of Teental which was seen above.
