The scales of Shubhapantuvarali (also called Shivapantuvarali) are as follows :
Arahonam (Ascending) : S R1 G2 M2 P D1 N3 S’
Avarohanam (Descending) : S’ N3 D1 P M2 G2 R1 S
Shubhapantuvarali is 45th on the Melakarta scale. It is similar to the Hindustani Raag Todi. This is one of my favourite ragas, highly charged with emotion and pathos, hauntingly sad. The most well known songs in this raga are Ennalu Orake by Tyagaraja and Sri Sathyanarayanam by Muthuswami Dikshithar. There are a few lesser known are kritis such as Ne Pogadukunte by Tyagaraja, Paripahimam by Mysore Vasudevachar, Ni Samana by G.N.Balasubramaniam etc but there are not many in number. The emotional nature of the raga makes it popular in film music.
Tamil speaking readers may enjoy this short presentation of the raga by Charulata Mani in her Isai Payanam series:
Note : The 12 notes in the octave are named as below. Please note that C is used as Sa for the sake of simplicity as the scale is relative in Carnatic Music. Also note that the scales paint only a superficial picture of the raga as the gamakas(ornamentations) are a very important part of a raga.
