This is an exercise where pair of Swaras are practiced in Mayamalavagowla Ragam. The pair Swaras are called Jandai Varisai.The pair here means two Swaras [ a pair]rendered for one unit of a Thalam. Therefore there will be eight pair Swaras in an Octave. Since there are 16 Swaras –by count- in an Avartham, this cannot be considered as second of speed. Here one pair is considered as one unit.
Also, there is another paadantharam taking one Swara for an unit of Thalam.
In Jandai Praogas, the first Swara is rendered plain and the second note in the pair rendered with a stress from its immediate lower note. This is called Spuritham
