India's classical arts grew out of temple ritual and storytelling, counted out in rhythm like mathematics. This section covers the great dance forms — Bharatanatyam, Kathak, Odissi, Kathakali — and the two vast systems of classical music, Hindustani in the north and Carnatic in the south, with their ragas tuned to times of day and seasons. There's the folk side too: the drums of a village festival, the ballads that carried history when no one wrote it down. Read about a single raga, a temple dancer, or an instrument older than most countries — the tradition runs deeper than any one lifetime.
