Niroshta

It is a derived scale (janya rāgam), as it does not have all the seven swaras (musical notes).

[1] Niroshta is a symmetric pentatonic scale (audava-audava ragam[1][2] in Carnatic music classification – audava meaning 'of 5') that does not contain madhyamam and panchamam.

Its ārohaṇa-avarohaṇa structure (ascending and descending scale) is as follows (see swaras in Carnatic music for details on below notation and terms): The notes used in this scale are shadjam, chathusruthi rishabham, antara gandharam, chathusruthi dhaivatham and kakali nishadham.

Muthiah Bhagavatar is credited with creating this scale, due to the fact that the King of Mysore had a bee sting in his lip and could not sing the Panchama and Madhyama notes, since the notes touch the lip while pronouncing it.

His melodious composition Raja Raja Radhite set to Rupaka tala (3/4 beat) also does not use the syllables Ma and Pa. Madurai T. N. Seshagopalan, a disciple of Ramanathapuram C. S. Sankarasivam, who in turn is a disciple of Muthiah Bhagavatar has composed a thillana in Niroshta "tanana dhirana" in Adi Tala.
