Dussehra might be a festival to celebrate the victory of good over evil, but it's only a minor part of Hindu mythology. Ravan was one of the most important characters ever in the scheme of things. He's seen mostly as a villain, but surely he's much more than that.
In many depictions of Ravan, he can be seen carrying a veena. It is believed that he had a keen interest in music and was a highly accomplished veena player.

Ravan's father was the famous rishi, Visravas, who himself was a son of Prajapati Pulastya, one of Brahma's ten 'mind-born' sons.
