Fourteen modal rotations of the two ancient grāmas — seven from ṣaḍja-grāma, seven from madhyama-grāma, the same grāma with pa lowered one pramāṇa śruti. Ahobala catalogues each as the root of a distinct rasa-palette; Carnatic ragas inherit from them through their preferred mūrchhanā.

Historical Rotation vs Modern Thāt Disclosure

Audition sounds the exact mathematical rotation intervals in 22-śruti JI. In post-medieval classification, Ahobala associates this mūrchhanā with modern Kāfī. The differences between the mathematical rotation and the associated thāt are preserved rather than obscured.
