A raga is a melodic framework for improvisation in Indian classical music akin to a melodic mode. Rāga is central to classical Indian music and a unique feature of the tradition: no equivalent concept exists in Western classical music. Each rāga consists of an array of melodic structures with musical motifs; and, from the perspective of the Indian tradition, the resulting music has the ability to "colour the mind" as it engages the emotions of the audience.

Indian classical music is the classical music of the Indian subcontinent. It is generally described using terms like Marg Sangeet and Shastriya Sangeet. It has two major traditions: the North Indian classical music known as Hindustani and the South Indian expression known as Carnatic. These traditions were not distinct until about the 15th century. During the period of Mughal rule of the Indian subcontinent, the traditions separated and evolved into distinct forms. Hindustani music emphasizes improvisation and exploration of all aspects of a raga, while Carnatic performances tend to be short composition-based. However, the two systems continue to have more common features than differences. Another unique classical music tradition from Eastern part of India, i. e. Odissi music has evolved since two thousand years ago.
