"Works dealing exclusively with the science of music were written during the Sangam period, but were lost long ago. The Silappthikaram of the second century AD throws flood of light on the music of the Tamils. Music in Tamil nomenclature is isai. They had five kinds of Pans (specific melody type), namely Mullai, Kurinji, Marudham, Neythal and Palai. Apart from this, they had seven musical notes, viz., Kural, Thuttam, Kaykkilai, Uzhai, Ili, Vilari and Tharam."
