This is an ancient rāga. It corresponds to Bhairav thāṭ 9 of Hindustani music. It consists of a pair of symmetrical tetrachords separated by a major tone interval.
This scale is also found in Bulgarian music. It is a mūrchanakāraka mēḷa 10. It gives rise to two other rāgas through the process of grahabhēda or modal shift of tonic, namely Rasikapriya from riṣabha and Simhēndramadhyama from madhyama.
It offers ample scope for improvisation. Owing to its symmetry as well as closely placed adjacent notes, Purandara Dasa chose this rāga for the beginners’ lessons starting from Saraḷe varase upto Alaṅkārams, as it is easier for children to pick up the notes. Malahari, which is the rāga of the Piḷḷāri gītams starting from Lambodara lakumikara, is a derivative of this rāga.
It is a tristhāyi rāga, that is, it can be sung in all three octaves. It is maṅgaḷakara or auspicious. Gāndhāra and niṣāda are rāgachāyā svaras11 . Besides ṣaḍja and pañcama, madhyama and niṣāda are nyāsa svaras12 . R-D, G-N are pairs of vādi-samvādi13 svaras.
It can portray rasas14 like karuṇā (compassion), śānta (tranquil) very effectively, just as it can convey the feeling of devotion or bhakti bhāva.
