Definition
Bhairav (thaat) is one of the ten fundamental parent scales (thaats) used in Hindustani classical music. It serves as a theoretical framework for grouping ragas that share a specific set of intervals, notably the inclusion of a komal (flat) Re (Rishabh) and a komal Dha (Dhaivata) while retaining shuddha (natural) Sa, Ga, Ma, Pa, and Ni.
Overview
In the system codified by musicologist Vishnu Narayan Bhatkhande in the early 20th century, each thaat is a seven‑note scale (saptak) that provides the tonal basis for several ragas. The Bhairav thaat is characterized by its solemn and meditative character, and ragas derived from it are traditionally performed in the early morning. Prominent ragas belonging to this thaat include Raga Bhairav, Raga Ahir Bhairav, Raga Nat Bhairav, and Raga Miyan ki Todi (in certain interpretations).
Etymology/Origin
The name “Bhairav” is derived from Bhairava, a fierce manifestation of the Hindu deity Shiva. The association reflects the thaat’s austere and devotional mood, which aligns with the spiritual attributes traditionally linked to the deity. The thaat, as a formal construct, was introduced by Bhatkhande as part of his effort to systematize Hindustani music into a taxonomy of ten parent scales.
Characteristics
- Scale (Arohana/Avarohana): Sa ♭Re Ga Ma Pa ♭Dha Ni Sa′ (ascending and descending use the same set of notes).
- Key Intervals: The thaat features a minor second between Sa and komal Re, and between komal Dha and Pa, creating a distinctive gravitas.
- Maqam Analogy: The interval pattern bears a superficial resemblance to the Phrygian mode in Western music, though the melodic treatment in Hindustani tradition follows different ornamental conventions.
- Emotional Tone (Rasa): Often described as “karuna” (pathos) or “bhakti” (devotion), suitable for contemplative and sunrise performances.
- Typical Ornamentation: Use of meend (glissando), gamak (oscillation), and slow alap (introductory improvisation) to emphasize the gravitas of the komal notes.
