It is a derived scale (janya rāgam), as it does not have all the seven swaras (musical notes).
It is called a shadava-shadava rāgam,[1][2] in Carnatic music classification (as it has six notes in both ascending and descending scales).
Its ārohaṇa-avarohaṇa structure is as follows (see swaras in Carnatic music for details on below notation and terms): This scale uses the notes shadjam, chathusruti rishabham, sadharana gandharam, shuddha madhyamam, chathusruthi dhaivatham and kaisiki nishadam.
It has only the invariant panchamam missing from its parent scale, Kharaharapriya.
[2] This scale has been used by many composers and there are many compositions in classical music.
