Naatai and Gaulai

Naatai is a janya of the 36th melakarta Chalanaatai. Teacher says that this ragam can be heard in a lot of dance programs. I find it interesting that this ragam depicts 'Veera' rasam. I have been listening to 'Kaithala niraikani' sung by Smt.M.S.Subbulakshmi, 'Jaya jaya' sung by Sri.K.V.Narayanaswamy and
'Sarasiruhasanapriye' sung by Bombay Jayashree.
Gaulai is a janya of the 15th melakarta Mayamalavagowlai. I have been listening to the renditions of 'Sree Maha Ganapathiravathumam' by Sri Maharajapuram Santhanam,
'Thyagaraja paalaya' by Sri Balamuralikrishna and 'Saraswathya Bhagavathya' by Sri BV Raman and Sri BV Lakshmanan. Some songs remind me a lot of its kartha ragam.
