Bhairavi { Hindusthani } / Sindhu Bhairavi [Karnaatik]
Bhairavi was a very well known Hindusthani Raag that was adopted into Karnaatik Paddhathi as Sindhu Bhairavi [ Bhairavi from the Sindhu Region ] since another famous Bhairavi Raagam already existed in Karnaatik Elucidations. Simplifying an elaborate meta tale of stylistic evolution . Sindhu bhairavi became endowed with repose, Bhavam and certain stylistic peculiarities which were not existant in the Hindusthani rendering of the equivalent Bhairavi Raag.
So some Hindusthani musicians have re-adopted the Karnaatik Sindhu Bhairavi as a new Raag.
Here I don't make that distinction since the essential bhaava is same. Here I render Sindhubhairavi which is also Hindusthani Bhairavi.
