Concept
Raga
Summary
A raga (, ɾäːɡ; also raaga or ragam or raag; coloring) is a melodic framework for improvisation in Indian classical music akin to a melodic mode. The rāga is a unique and central feature of the classical Indian music tradition, and as a result has no direct translation to concepts in classical European music. Each rāga is an array of melodic structures with musical motifs, considered in the Indian tradition to have the ability to "colour the mind" and affect the emotions of the audience.
Each rāga provides the musician with a musical framework within which to improvise. Improvisation by the musician involves creating sequences of notes allowed by the rāga in keeping with rules specific to the rāga. Rāgas range from small rāgas like Bahar and Shahana that are not much more than songs to big rāgas like Malkauns, Darbari and Yaman, which have great scope for improvisation and for which performances can last over an hour. Rāgas may change over time, with an example being Marwa, the primary development of which has been going down into the lower octave, in contrast with the traditional middle octave. Each rāga traditionally has an emotional significance and symbolic associations such as with season, time and mood. The rāga is considered a means in the Indian musical tradition to evoking specific feelings in an audience. Hundreds of rāga are recognized in the classical tradition, of which about 30 are common, and each rāga has its "own unique melodic personality".
There are two main classical music traditions, Hindustani (North Indian) and Carnatic (South Indian), and the concept of rāga is shared by both. Rāga are also found in Sikh traditions such as in Guru Granth Sahib, the primary scripture of Sikhism. Similarly, it is a part of the qawwali tradition in Sufi Islamic communities of South Asia. Some popular Indian film songs and ghazals use rāgas in their composition.
Every raga has a svara (a note or named pitch) called shadja, or adhara sadja, whose pitch may be chosen arbitrarily by the performer.
