Nat Bhairav (or also written as Nut Bhairav) (Hindi: नट भैरव) is a Hindustani classical heptatonic (Sampurna) raga of Bhairav Thaat. Traditionally it is a morning raga. It is one of the most important ragas of the Bhairav anga.^[1]

This raga is not be confused with the Natabhairavi, the 20th Melakarta of Carnatic Music.^{[citation needed]} Sarasangi, which is the 27th Melakarta in Carnatic music, has the same scale as the Nat Bhairav in Hindustani music. In Western theory it is called the harmonic major scale.^{[citation needed]}

Writing about the musical theory of Hindustani music is fraught with complications. Firstly, there have been no set, formal methods of written notation. Secondly, Hindustani music is an aural tradition, and therefore writing is not an essential part of learning. However, Nat Bhairav is a morning raga. The raga reflects the mood of slight pathos with heroic exuberance.

While the above is true, modern (20th century) treatment of the Raga is slightly different. The basic Chalan of the Raga has de facto shifted the Vadi-Samvadi (Point-Counterpoint) duo to Re-Dha; and the basic characteristic phrase has become Re-Dha-Re, Re-Ga, Ga-Ma, Ma-Pa; Ma-NiDha-Pa, Ga-(Ma)-Re-Sa; Sa-'NiSa-'Dha.

It is believed that this Chalan brings out clearly the Nat-ang in Nat Bhairav.

As the name suggests, this raga is a combination of Nat and Bhairav (Shah [Bhairav ke Prakar] 1991: 255). It is regarded as one of the varieties of Bhairav. The lower tetra chord has the notes of Nat whereas in the upper tetra chord Bhairav is evident. Therefore, except Komal Dha, all the other notes are natural. The raga comes across as a musical entity with heroic exuberance, along with a slight feeling of pathos.
