An Ode to Mother Bengal, it was written by Bengali polymath Rabindranath Tagore in 1905 . The melody of the hymn derived from the Baul singer Gagan Harkara's song "Ami Kothay Pabo Tare" (আমি কোথায় পাবো তারে) set to Dadra Tala </P> <P> The word sonar literally means' made of gold' or' beloved', but in the song sonar Bangla may be interpreted to either express the preciousness of Bengal or refer to the colour of paddy fields before harvest . </P>
