S-g-mM-P-n-S

---

A rare hexatonic raga which instantly gripped my ears as a match for the Western ‘Blues Scale’ (SgmMPnS) when I came across a mellifluous rendition by sarangi master Abdul Latif Khan – who regularly utilises distinctly bluesy double-Ma phrases such as nSgmM, PMmgS (as per his student Nicolas Magriel: “His bandish is somewhat reminiscent of the Pink Panther theme”). Further research suggested that the raga was introduced by Dagarvani vocalists Zia Fariduddin Dagar and Ritwik Sanyal, although I’ve struggled to unearth much detail on their process of inspiration – despite the raga’s seemingly transglobal elements, it is unclear if its creators actually had the blues in mind while devising it. After all, Shrutivardhini differs from the American blues idiom in several notable ways: with many artists omitting shuddha ma in ascent, and most allowing tivra Ma to function as an independent swara (compared to its more ornamental role in the blues, where it is often hinted at via subtle upward bends from ma). Also recorded by Abdul Latif Khan’s son Farooque Lateef Khan and grandson Sarwar Hussain Khan (lehra transcribed below), as well as by Dhrupadyas Nirmalya Dey, Seuli Chakraborty, and Suvir Misra (who uses his rudra veena’s wide meend capabilities to summon the sounds of a slide guitar). The same SgmMPnS scale – a Ma-murchana of Marwa – has also been performed by Rahul Bhatt under the name ‘Madhusurawali’, said to be a creation of his father Balwantrai Bhatt ‘Bhavrang’. Compare to its ‘single-ma’ cousins Dhani (only ma) and Madhukauns (only Ma), as well as to other blues-inclined ragas such as Jog (which outlines a 7#9 ‘Hendrix’ chord) and Kalavati (which matches the classic SGPDn ‘boogie-woogie bassline’).
