This is a layavinyasam program on Doordharshan (TV) in the 80’s. The violinist, who is putting thalam for most of the program, is Sikkil Bhaskaran.
What one should take note of is his unhurried, thorough treatment of chatusra nadai initially and then tisra gathi. From a superficial perspective, his style may not have the fancy flair or breakneck speed of other mrudangam vidwans; what is noteworthy is his intellectual approach to music. Almost all of this is improvised on the spot, although there are a few bits (like the korvais and mohara) that are prewritten.
He uses a korvai to transition from chatusram to tisram. This is not very commonly done, and takes great skill to pull of in an aesthetically pleasing manner.
Also, one should take note of his posture. Even at his age, he is sitting with the correct posture. Maintaining the correct posture is not a trivial thing, especially with a heavy mrudangam on your leg, but it is necessary in order to be able to deliver the goods, so to speak. Increasingly, more and more artists today are not sitting with the correct posture, setting a bad example for the younger aspirants. This is not a healthy trend, but can be checked if one is informed at an early age.
