How about analysing this raga/Kritis in this raga?I have just heard Neela Ramgopal rendering MD's Kriti "Sri Thyagarajasya " -in this raga-Janya of Karaharapriya.
There's a famous kriti "Amba paradevathe", a composition of Shri Krishnaswamy ayya. The aro:avo of this ragam is srgmpdns snpmgrs and is a janyam of k.h.priya...but I do wonder what MD would have considered the janaka ragam of Rudrapriya to be.
