• Raag Chandramadhu •


An angular pentatonic form conjured up by vocalist Amir Khan only a short time before his untimely death in a 1974 car accident – indeed, it is unclear if he ever formally named his new creation (I’ve seen it referred to as ‘Bhushwati’ and ‘Amarpriya’, and at least two posthumous releases just list it as ‘Untitled Raga’). A detailed RMIC thread discusses several plausible origin theories, generally linking the raga’s genesis to an intricate murchana process involving Chandrakauns and Madhukauns: it is prakriti with the latter, and Khan may well have made no practical distinction between the pair – however, given the general sparsity of information, it is unclear which recordings count as ‘true’ renditions. Bewitching in its oddities (‘Dhani tivra Ma‘ / ‘Minor Pentatonic #4‘).
