composed in Telugu or in Sanskrit.

due to the excellence of their compositions.
It is well known that there were many forerunners of great composers who
wrote in Tamil These
compositions are poetically excellent

They were Muthu Thandavar (?1560 - ?1640 CE), Arunachala Kavi (1712–1779) and Marimutthu Pillai (1717–1787), and lived five
decades before the Tiruvarur Trinity or Trinity of Carnatic Music. They introduced
several innovations that led to the evolution of the Carnatic Kriti (song).Oothukadu
Venkada Subbayyar, Gopakrishna Bharathi , Arunachala Kavi are examples.
