The two great classical traditions of Indian music — Hindustani and Carnatic — and their underlying grammar of raga and tala.
Indian classical music traces its theoretical roots to the Sama Veda and later texts like the Natya Shastra, and today exists in two major traditions that diverged around the 13th–14th century: Hindustani music (North India, shaped significantly by Persian/Central Asian influence under the Delhi Sultanate and Mughals) and Carnatic music (South India, which retained a more direct continuity with ancient Sanskrit musicology).
Both traditions are built on the twin concepts of raga (a melodic framework of notes with defined ascending/descending patterns and mood) and tala (rhythmic cycle). A raga is not a fixed tune but a set of rules within which a performer improvises; talas are counted in cycles of beats (e.g. Teentaal in Hindustani music has 16 beats, Adi Tala in Carnatic music has 8).
Hindustani music is organised into gharanas — hereditary schools/lineages of stylistic practice, each associated with a particular vocal or instrumental approach, typically named after the town of origin. Prominent gharanas include Gwalior (the oldest khayal gharana), Kirana, Agra, Jaipur-Atrauli, and Patiala. Major forms include Dhrupad (the oldest surviving form), Khayal (the dominant modern form), Thumri and Ghazal.
Carnatic music is more composition-centred, built around fixed compositions (kritis) by the "Trinity of Carnatic Music" — Tyagaraja, Muthuswami Dikshitar and Syama Sastri — all active in the late 18th–early 19th century in the Thanjavur region. Carnatic performances follow a structured format within a concert (kutcheri), including varnam, kriti, and the improvisational ragam-tanam-pallavi.
The Sangeet Natak Akademi, India's national academy for music, dance and drama, confers fellowships and awards recognising eminent practitioners, and works alongside the Padma awards in honouring classical musicians. Renowned exponents across both traditions — from Bhimsen Joshi and Ravi Shankar to M.S. Subbulakshmi and Semmangudi Srinivasa Iyer — are frequently referenced in current affairs around Padma award announcements and Republic Day.
Prelims frequently tests matching instruments to their tradition/region and the names within the Carnatic Trinity. Mains rewards discussing Indian classical music as a living, syncretic heritage — the Persian influence on Hindustani music being a useful example of cultural synthesis under the Delhi Sultanate/Mughals.
