What music do surbahar players perform?

The surbahar's core repertoire is alap, jor and jhala in the dhrupad-derived style, and a player may follow with a slow dhrupad composition accompanied by pakhawaj. In the Imdad Khan family, musicians played a rudra-veena-style alap on surbahar and then the composed bandishes on sitar. In Annapurna Devi's gharana the surbahar was used for alap-jod-jhala, occasionally with tar paran and dhrupad compositions.
