The main emphasis in Carnatic music is on vocal music; most compositions are written to be sung, and even when played on instruments, they are meant to be performed in gāyaki (singing) style. The heptatonic scale is known to have its origins in Carnatic music, and later having been picked up by Pythagoras during his visit to India to learn mathematics, thus introducing it to the west. The circle of fifths and several other popular concepts in western classical music have their origins in the theory of Carnatic classical music.

The history of southern India covers a span of over four thousand years during which the region saw the rise and fall of a number of dynasties and empires. The period of known history of the region begins with the Iron Age period until the 15th century CE. Dynasties of Chera, Chola, Pandyan, Chalukya, Pallava, Satavahana Rashtrakuta, Kakatiya, Reddy dynasty, Seuna (Yadava) dynasty and Hoysala were at their peak during various periods of history. These Dynasties constantly fought amongst each other and against external forces when northern armies invaded southern India. Vijayanagara empire rose in response to the Muslim intervention and covered the most of southern India and acted as a bulwark against Mughal expansion into the south. When the European powers arrived during the 16th and 18th century CE, the southern kingdoms, most notably Tipu Sultan's Kingdom of Mysore, resisted the new threats, and many parts eventually succumbed to British occupation. The British created the Madras Presidency which acted as an administrative centre for the rest of South India, with them being princely states. After Indian independence South India was linguistically divided into the states of Tamil Nadu, Andhra Pradesh, Karnataka, Telangana and Kerala.
