Hi Renuka,Sanskrit, Carnatic Music, literature have always been the preserve of the TBs. Only carnatic dance was taken up by the TBs after the devadasi system was abolished.All the carnatic music songs were/have been composed by the South Brahmins. After the fall of the Brahmin empire, the Brahmins have preserved the culture & traditions intact right through the generations!! Other members can add here, to my knowledge, I don’t think NBs were involved in Carnatic music anytime in the historic past. For eg, Ravana is the originator of Veena as per our texts. Because Sanskrit is our true mother tongue, the Brahmin Tamil is 80% sanskritized. For eg, the Telugus settled in Tamil Nadu speak a Tamil with many Telugu words. So no race will ever forget their mother tongue, it continues in their dialect in some form or other !!Other than Carnatic music, the rest of the music/traditions were preserved by NBs. On a side note, there is NOTHING called Dravidian languages as all the south languages including the Sinhala language are highly sanskritised. Only true Dravidian language is the one spoken by the Aborginals in Australia, this is totally untouched by any intermixing to this date. That’s why it sounds like Tamil/Telugu/Kannada etc…Cheers,
