The scales of Madhyamavati are as follows :
Aarohanam (Ascending) : S R2 M1 P N2 S’
Avarohanam (Descending) : S’ N2 P M1 R2 S
Madhyamavati is a janya raga, derived from Kharaharapriya (below), 22nd on the Melakarta Scale.
Madhyamavati is normally sung near the end of a concert as it is said to wash away the sin of singing wrong notes! It is also appropriate for elaborations as the notes are well spaced. There are very many popular compositions in this raga, some of which are Adathu asangathu va kanna by Oothukadu Venkata Subbaiyyar, Nagumomu galavani and Rama Katha Sudha by Tyagaraja, Karpakame by Papanasam Sivan and Palinchu Kamakshi by Shyama Shastri.
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.
