Desh is a Hindustani classical raga.
Desh (raga) Wikipedia
The raga is of Audav-sampurna nature, i.e., in its arohana (ascent) only five notes are used, whereas the avarohana (descent) uses all the seven notes. Shuddha Ni is used in the arohana, while Komal Ni (represented as ni below) is used in avarohana. All other swaras are shuddha.
Arohana: Ni Sa Re, Ma Pa Ni,Sa.
Avarohana: Sa ni Dha, Pa Dha Ma Ga Re, Pa Ma Ga, Re Ga Ni Sa.
Pakad: Re, Ma Pa Ni, Sa Re ni Dha Pa,ma Ga Re
The vadi swara is Re
The raga is to be sung during the second quarter of the night (6PM to 9PM )
Re is very prominent, quite a few times the singer rests on Re, making it a centre to the melody. The Meend from Ma to Re via Ga is one of the most vital features of the raga. The arohana via shuddha Ni, and the transition from Re to komal Ni in the avarohana form an important part of the melodies in this raga. Further, Desh is quite close to neighboring ragas like Tilak Kamod, and hence requires skilful rendition to separate itself.
Desh has been used in patriotic compositions. Vande Mataram, the national song of India, is the most well-known. The popular old Doordarshan video Baje Sargam, that featured many respected Indian classical singers, is also based on Desh.
The polymath and Nobel laurete, Rabindranath Tagore, had very often used Hindustani Classical Music and Carnatic Classical Music in his songs (Rabindrasangeet). The songs based on this raga Des are listed below:
