| komal Ni, shuddha Dha, komal Ni, komal Re, Sa | is the most characteristic run, where the Ni and Dha belong to the lower octave and the Re and Sa are from the middle octave. There is typically some andolan/oscillation at the flattened second (komal Re).
Also there may be impressions of Kafi, the image of Ahir Bhairav is easily maintained with the characteristic passage ṇ Ḍ ṇ/r~ S Specially the characteristic Bhairav andolan (oscillation) on komal re. Sometimes shuddha Ni is used in the lower octave to emphazise the Bhairav character.
The Carnatic music equivalent to this raga is Chakravakam.
