Indian music began as an integral part of socio-religious life in ancient times, with references to string and wind instruments in the Vedas. It flourished during the Mughal empire and has been used to instill patriotic feelings in Indians. Various folk music traditions emerged across Indian regions, such as Bihu dances in Assam celebrating the new year and the earth. A prominent Indian instrument is the sitar, a string instrument with movable frets and 18 to 20 strings.
