Jana Gana Mana Written in Sanskritised Bengali, it is the first of five stanzas of a Brahmo hymn composed and scored by Nobel laureate Rabindranath Tagore.

         It was first sung at the Calcutta Session of the Indian National Congress,on 27 December 1911. Jana Gana Mana was officially adopted by the Constituent Assembly as the Indian national anthem on January 24, 1950. The music for the "current version" is said to be derived from a composition for the song by Ram Singh Thakur, although some dispute this.

 The composition consisting of the words and music of the first stanza of the late poet Rabindra Nath Tagore's song known as "Jana Gana Mana" is the National Anthem of India. It reads as follows:

Jana-gana-mana-adhinayaka, jaya he
Bharata-bhagya-vidhata.
Punjab-Sindh-Gujarat-Maratha
Dravida-Utkala-Banga
Vindhya-Himachala-Yamuna-Ganga
Uchchala-Jaladhi-taranga.
Tava shubha name jage,
Tava shubha asisa mange,
Gahe tava jaya gatha,
Jana-gana-mangala-dayaka jaya he
Bharata-bhagya-vidhata.
Jaya he, jaya he, jaya he,
Jaya jaya jaya, jaya he!

Thou dispenser of India's destiny.
