Whatever I learned that, this is the speciality of raag Hindole, where in aroha only 4 notes are used ( which doesn't full fill the criteria for a raag ), but Dhaivat is used along with the touch of Nishad as kon / sparsha swara....
Malkauns Bhairav Hindole Megh Shree and the infamous Deepak These 6 ragas are very old and sacred. Malkauns is my favourite. Although Deepak seems to have been lost.
I have heard, miya Tansen died while singing raag deepak. It was very powerful raag which used to generate fire. I guess there is two raag deepak from different thaats. But the raag which Tansen sung is sadly distinct
इसके जो आरोह-अवरोह आपने गाके बताए वो तो 4 ही स्वर हुए । उस दृष्टि से तो ये राग की श्रेणी में ही नहीं रखा जा सकता । कम से कम 5 स्वर तो होने ही चाहिए । कुछ पुस्तकों में शुद्ध निषाद का प्रयोग भी कहा गया है । वो क्या है फिर ? कृपया confusion दूर करें ।
