This is an ancient rāga that dates back to the period of the grāma-mūrchana-jāti system10 . It corresponds to Kalyāṇ thāṭ 11 of Hindustani music. It coincides with the Lydian mode of western music. It is a mūrchanakāraka mēḷa 12.
It gives rise to five other rāgas through the process of grahabhēda or modal shift of tonic. The five rāgas are Harikāmbhōji from riṣabha, Naṭhabhairavi from gāndhāra, Śaṅkarābharaṇa from pañcama, Kharaharapriya from dhaivata and Tōḍi from niṣāda. It is a major rāga that offers ample scope for improvisation.
There are a number of compositions covering almost all varieties of compositional forms. It is a tristhāyi rāga, that is, it can be sung in all three octaves. Riṣabha, Gāndhāra, and niṣāda are the rāgachāyā svaras13 .
Besides ṣaḍja and pañcama, riṣabha, gāndhāra and niṣāda are the nyāsa svaras14 . R-P, R-D, G-D, G-N, M-N are pairs of vādi-samvādi svaras15 .
It can portray rasas16 like karuṇā (compassion), adbhuta (wonder), śṛṅgāra (romance), vīra (valour) very effectively, just as it can convey the feeling of devotion or bhakti bhāva.
