Composers, composers.......

To the vast hordes of non-learners of Carnatic music, and sadly, even to some learners, "composers" as a term generally refers to the musical Trinity, and a select few others. To be frank, that was the case with me as well till about two years ago, when I began exploring lesser known composers. And stumbled upon a mine!
It took me another year to realise that these were not really lesser known composers, it was just a question of my own ignorance. A humbling, educational experience!
Among the composers I "discovered" were Subbaraya Sastri and Annaswamy Sastri, both descendants of Sri. Shyama Sastry, eldest of the musical trinity. In particular, the compositions of Subbaraya Sastri interested me, and though I did not learn many, I collected a number of his works from books on the subject, chiefly from Smt. Vidya Shankar's book on his compositions.
Anyway, getting back to where I began, I can perhaps answer my own statemnt-question: the very fact that the Trinity continue till date to hold their sway over all other composers of calibre explains why they do!
