In Hindustani classical music, the structure and emotive essence of a raga are shaped by the roles of specific notes, categorized as Vadi, Samvadi, Anuvadi, and Vivadi. The Vadi is the most prominent note in a raga, often referred to as the “king” note. It is emphasized frequently and serves as a focal point in the melodic development, anchoring the raga’s identity. The Samvadi, considered the “minister” or “vizier,” is the second most significant note, typically located a fourth or fifth interval from the Vadi. Together, the Vadi and Samvadi establish the raga’s tonal framework and are pivotal in conveying its mood and character .
The Anuvadi notes are the remaining notes in the raga that are neither Vadi nor Samvadi. They function as supportive tones, enriching the raga’s melodic expression without overshadowing the primary notes. In contrast, Vivadi notes are considered dissonant or foreign to the raga’s structure. Traditionally avoided to maintain the raga’s purity, skilled musicians may occasionally incorporate Vivadi notes subtly to introduce tension or enhance the raga’s beauty. This nuanced use of Vivadi notes requires a deep understanding of the raga’s framework to ensure they complement rather than disrupt the intended emotional expression.
