A raga for relief: How Bhairavi found its way into the lab

In a rare confluence of classical artistry and modern neuroscience, researchers at Birla Institute of Technology, Mesra, have offered scientific validation to something Indian musicians have long intuited — that music heals. A breakthrough study led by Prof. Mrinal Kumar Pathak, an accomplished classical musician and academic from BIT Mesra’s Department of Humanities and Social Sciences, has revealed that Raga Bhairavi, when played on the flute at a soft 15 decibels, can trigger measurable pain relief.

Published in Current Psychiatry Research and Reviews, the paper — titled “Pain Alleviation through Raga Bhairavi (15dB, Flute): Activation of the Hypothalamus-pituitary Axis and �-endorphin–cAMP Pathway in Swiss Albino Mice” — marks a pioneering stride for Indian musicology-driven therapy. What makes the work exceptional is that it does not merely claim the soothing influence of classical music; it documents biochemical evidence. Through controlled exposure to Raga Bhairavi, the research team observed activation of the HPA (hypothalamus–pituitary–adrenal) axis and release of �-endorphins — the body’s natural analgesics — in Swiss Albino mice.

The neurochemical response triggered a statistically significant reduction in pain sensitivity, placing the raga in serious scientific conversation. The study’s conception owes much to Prof. Pathak’s unusual trajectory — one that straddles classical performance, composition, and academic inquiry. With years steeped in the grammar and aesthetics of Hindustani classical music, he brings an intuitive understanding of ragas to the rigour of laboratory research. It is precisely this blend of aesthetic insight and empirical discipline that shap ed the experiment.“Music is not merely an art form; it is a neurochemical force,” Prof. Pathak often tells his students. His work appears to prove just that. Collaborating with him was Prof.

Shakti Patnaik of BIT Mesra’s Department of Pharmacy, currently engaged in research in the United States. Patnaik’s pharmacological expertise strengthened the study’s biochemical analysis, adding depth to what could have otherwise been a purely auditory inquiry. The interdisciplinary lens — weaving music, pharmacology, and neuroscience — is what sets the project apart. For BIT Mesra, the research signals a significant milestone, placing the institution at the forefront of scientific explorations rooted in India’s traditional knowledge systems. More broadly, it reinforces India’s potential to contribute culturally grounded, non-invasive therapies to global medical practice.

At a time when the world is increasingly turning to alternative and drug-free therapies for pain and psychiatric conditions, the validation of Raga Bhairavi’s analgesic effect opens vast possibilities. From mental health institutions to palliative care units, the idea of prescribing music — not metaphorically, but biochemically — may no longer be far-fetched. Prof. Pathak’s work also calls upon universities and research institutions to support cross-disciplinary ventures. His journey underscores how innovation often emerges from the intersection of fields traditionally kept apart.

By rooting contemporary science in indigenous traditions, studies like this reassert the relevance of India’s classical heritage in a rapidly modernising medical landscape. The flute strains of Raga Bhairavi, long associated with calmness and closure in the classical repertoire, have now found affirmation in the language of enzymes and neural pathways. In bridging these worlds, Prof. Pathak stands out as a scholar-artist whose research may well reshape the future of music-based therapy — one raga at a time.
