Raga Bibhas or Vibhas
Bibhas is a Hindustani classical raga. Bibhas (sometimes also called 'Vibhas') is a pentatonic raga belonging to the Bhairav Thaat. This Raga is sung during daybreak. It is quite similar to raga Deshkar as changing the Shuddha Dha and Shuddha Re of Deshkar converts it into Bibhas. The true nature of Bibhas has Re and Dha flat. However, it is very rarely performed using the Shuddha Dha. In order to maintain the pure character of Bibhas, it is very important that Pa is not the last note during any alap or taan. The atmosphere created by this raga is serious, as it has Komal 'Re' and 'Dha'.
By changing Rishabh aur Dhaivat Komal in Raag Deshkar, raga Vibhas comes into existence. In this raga, Rishabh and Dhaivat are not oscillating as in raga Bhairav. This raga has a rather heavy feel and is perfect for Bhakti Ras.
