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). Also see other ragas which Shankar helped bring to broader attention (e.g. Asa Bhairav & Nat Bhairav) – plus his Carnatic imports (Charukeshi, Vachaspati, Kirwani, Malay Marutam, & Simhendra Madhyamam).
