Sitars are a northern Indian stringed instrument of the lute family. They are the dominant instrument in Hindustani music. They appear to have developed under Medieval Muslim influence from the tanbur, a Middle Eastern long-necked lute and from the vina, or bin, a narrow, elaborate Indian Zither. Iconographic images of instruments similar to the modern sitar appeared only around 1800. There is abundant proof that the instrument had taken on its present form by the mid-nineteenth century. Several additional innovations during the turn of the twentieth century have been made to the instrument since then, giving form to the current "standard" sitar.
