Veena Naadam understanding the Difference

There are only few opportunities, one would get, to understand the Naadam of an acoustic musical instrument specially string instrument and in those very specifically Veena, sitar n violin.
I'm Ganesh Prasad from ARUNA Musicals Bengaluru., documenting this video, to just share an idea how one can parallelly compare Naadam of different veenas of same type or kind.
