This north Indian dance form is inextricably bound with classical Hindustani music, and the rhythmic nimbleness of the feet is accompanied by the table or pakhawaj. Traditionally the stories were of Radha and Krishna, in the Natwari style (as it was then called) but the Moghul invasion of North India had a serious impact on the dance. The dance was taken to Muslim courts and thus it became more entertaining and less religious in content. More emphasis was laid on nritta, the pure dance aspect and less on abhinaya (expression and emotion)
