· Purvang, Uttrang, and Samvadi are all fundamental concepts integral to the internal structure and theory of a Raga in Indian classical music.
· They describe the raga's architecture and hierarchy of notes.
· In stark contrast, Chords refer to the harmonic practice of sounding three or more notes simultaneously, which is a cornerstone of Western harmony but not a structural element of a traditional Indian raga, which is fundamentally melodic and linear.
· A Raga is analysed through various structural components.
· Purvang refers to the lower tetrachord (the first four notes: Sa, Re, Ga, Ma).
· Samvadi is the second most important note in a raga, forming the chief consonant interval with the Vadi (most important note).
Additional Knowledge:
· The odd one out is determined by the conceptual domain.
· The first three belong to Indian melodic theory, while Chords belong to Western harmonic theory, making it the foreign element in the list.
