Malkauns, known also as rag Malkosh, is a raga in Indian classical music. It is one of the oldest ragas of Indian classical music. The equivalent raga in Carnatic music is called Hindolam, not to be confused with the Hindustani Hindol.
According to Indian classical vocalist Pandit Jasraj, Malkauns is a raga that is "sung during small hours of the morning, just after midnight." He further adds that the raga has a soothing and intoxicating effect.
A raga (/ˈrɑːɡə/ RAH-gə; IAST: rāga, Sanskrit: [ɾäːɡɐ]; lit. 'colouring', 'tingeing' or 'dyeing') is a melodic framework for improvisation in Indian classical music akin to a melodic mode. It is central to classical South Asian (Indian, Pakistani and Bangladeshi) music. Each raga 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.
Each raga provides the musician with a musical framework within which to improvise. Improvisation by the musician involves creating sequences of notes allowed by the raga in keeping with rules specific to the raga. Ragas range from small ragas like Bahar and Sahana that are not much more than songs to big ragas like Malkauns, Darbari and Yaman, which have great scope for improvisation and for which performances can last over an hour. Ragas 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 raga traditionally has an emotional significance and symbolic associations such as with season, time and mood. Ragas are considered a means in the Indian musical tradition for evoking specific feelings in listeners. Hundreds of ragas are recognized in the classical tradition, of which about 30 are common, and each raga has its "own unique melodic personality".
Hindōḷaṃ is a ragam in Carnatic music (musical scale of South Indian classical music). It is an audava rāgam (5 notes in arohana and avarohana) as it does not have all the seven swaras (musical notes). Hindolam is not the same as the Hindustani Hindol. The equivalent of Hindolam in Hindustani music is Malkauns (or Malkosh).
It is known to be a rāgam that is generally beautiful and soothing to listen to. Being symmetrical in its ascending and descending scales, it lends itself very well to improvisation and is therefore popular at concerts.
