Bilawal

Raga Bilawal is the parent raga of the Bilawal thaat and is considered the most foundational of all Hindustani ragas, the one from which the entire theoretical system of thaats radiates outward, because its scale — all seven shuddha (natural) swaras, Sa Re Ga Ma Pa Dha Ni — corresponds to the pure, unaltered baseline from which every other raga is defined by deviation.

Ancient Sanskrit musicological texts reference a scale of this configuration under various names (Shadja-Gram, Bilaval), suggesting that this natural heptatonic scale has been the theoretical north star of South Asian music for over two thousand years.

The raga belongs to the morning hours and is classified as a sandhiprakash raga — one associated with the transitional light of dawn — and its bright, luminous, untroubled character is understood as the sonic analogue of the rising sun: clarity, openness, and the renewal of possibility.

In performance, Bilawal demands extraordinary subtlety from the artist precisely because its scale contains no altered swaras to create dramatic colour; the raga's beauty must emerge from phrase-shape, ornament, and the nuanced treatment of the vadi Dha and samvadi Ga, which give it a warm, devotional character distinct from the brightness of a mere major-scale exercise.

Pandit Bhimsen Joshi's expansive morning renditions of Bilawal are regarded as paradigmatic expressions of the raga's serene grandeur; Ustad Faiyaz Khan left recordings of Bilawal that defined the agra gharana's approach for generations.

Many auspicious morning bhajans and classical compositions in Bilawal have been sung at temple performances and dawn concerts across the subcontinent for centuries.
