Raga Bhinna-Shadja or Raga Kaushik Dhwani
The ancient raga Bhinna-Shadja is presently known as Kaushik-dhwani. Even though its plaintive tone is moderate, the rest of its tones are just as important on which it can be paused. For this reason, this raga has complete freedom of expansion and can be sung easily in all the three octaves.
The use of Gamak and Meend helps in beautification of the Raag. In Avroh, rendering S' D in Meend seems more melodious then the straight forward S' N D. This Raag creates a deep and soothing atmosphere.
Bhinna Shadja is a raga of Hindustani classical music belonging to the Bilaval Thaat (Melakarta No. 29 Dheerashankarabharanam). It contains five Shuddha Swaras: Shadaja, Gandhar, Madhyama, Dhaivata, and Nishad. Rishabh and Pancham are omitted. In the form of notation it contains S,G,M,D and N.
In Carnatic music, these five swaras are termed Shadja -Sa, AntaraGandhar - ga, Suddha Madhyama - ma, Chatusruti Dhaivata - dhi and KakaliNishad - nu.
In western classical notation, the notes are termed tonic, perfect third, perfect fourth, perfect sixth, and perfect seventh; i.e., C, E, F, A and B; second D and fifth G notes are omitted.
Raga Bhinna Shadja is known by many alternative names such as Audawa Bilawal, Bhookosh, Dinka Malkosh, Koushikdhwani, and Kousidhani.
