S-R-G-m-P-D-N-S

---

Often cited as an invention of Ravi Shankar, Hem Bihag was in fact devised by his teacher Allauddin Khan – as noted by Shankar & Ali Akbar Khan when they chose it to open a tribute concert just a few weeks on from their guru’s 1972 death, at the reputed age of 110 (below: “we begin with a creation of his, a night raga…”). Allauddin himself never recorded it (although you can hear him exploring both its parents on the violin: Hem & Bihag) – meaning that modern renditions instead follow after Shankar, Ali Akbar, and Nikhil Banerjee‘s various takes, which tend to exhibit a weak Dha, strong Ni, and the avoidance of Re in aroha. The ‘Hem’ in the name refers to Hemant – another Khansaab invention which builds from a Bhinna Shadja base – rather than Khem Kalyan (although I’ve heard occasional mention of another, older species of ‘Hem Bihag’, which does draw from the latter raga).
