Bhairavi is one of the most beloved and emotionally rich ragas in Hindustani classical music — so central and so all-embracing that it is often called the "queen of ragas." It is the namesake of the Bhairavi thaat, and in its pure form it is a sampurna raga using all komal (flat) notes except Sa: komal Rishabh, komal Gandhar, shuddha Madhyam, komal Dhaivat and komal Nishad. In practice, however, Bhairavi is famous for being sung with great freedom, and skilled musicians introduce all twelve notes into it, making it one of the most flexible and expressive ragas of all.
Although it is technically a morning raga, Bhairavi occupies a special ceremonial role: it is traditionally sung as the last piece of a concert, regardless of the hour. Its sweet, devotional, deeply moving character makes it the perfect way to send an audience home with a full heart, and so "ending with Bhairavi" has become a cherished convention of Hindustani music.
It is important not to confuse this Hindustani Bhairavi with the Carnatic Bhairavi, which is an entirely different raga sharing only the name. The Carnatic Bhairavi is a specific janya raga with two dhaivatas; the Hindustani Bhairavi is an all-komal, endlessly flexible raga associated with concert conclusions, bhajans and thumris.
Students love Bhairavi because it is at once approachable and infinitely deep. Its basic all-komal scale is easy to learn, but its freedom — the way great artists weave in outside notes and shape endless expressive phrases — means it rewards a lifetime of study. Its tender, devotional mood makes it wonderful for emotional singing and for the light classical forms in which it so often appears.
The repertoire and popular legacy are vast. The immortal thumri "Babul Mora Naihar Chhooto Jaye" is set in Bhairavi, and countless bhajans, thumris and film songs live in its world — the devotional "Duniya Banane Wale" from Teesri Kasam, the tender "Beeti Na Bitai Raina" from Parichay (a Bhairavi-hued classic), and innumerable others. Few ragas are as woven into the emotional fabric of Indian music.
