The origins of classical Indian music is said to date back to over 5000 years ago. Basically this genre of music came about to serve a spiritual purpose. The melodies that were composed brought about feelings of peace, calm, tranquility, serenity, bliss and a closer bond with god. In fact according to the Vedas, music is considered to be a divine gift to humanity.
