Bow attachment made of an elastic material for a bow of a stringed instrument, wherein the bow attachment is made of an elastomer, comprising: an oblong support element, which has been adapted to lie on a grip end of the bow stick, and which essentially has the shape of an arc when viewed in the longitudinal direction; a first and a second fastening element (16, 18), which are attached to the two ends of the oblong support element, wherein the first fastening element is adapted to be attached to the bow-stick end, and the second fastening element is adapted to be attached to the bow stick; a first grip surface attached to a first longitudinal side of the support element; a stabilizing surface and a second grip surface, which are attached to a second longitudinal side of the support element opposite the first grip surface; wherein a first section of the first grip surface and the stabilizing surface are adapted to be at least partially attached to opposite sides of a bow frog, wherein the first section of the first grip surface and the stabilizing surface are arranged adjacent to the first fastening element; wherein a second section of the first grip surface and the second grip surface are adapted at least partially to lie on opposite sides of the bow stick and each have a width perpendicular to the longitudinal side of the support element, which are adapted to be less than the distance of tensioned bow hair to a top side of the bow rod, wherein the second section of the first grip surface is arranged adjacent to the second fastening element and the second grip surface is arranged adjacent to the stabilizing surface, and wherein the support element, the stabilizing surface and the first and second grip surfaces (8, 10) are provided with nubs; characterized in that the support element has a length within a range of 8 cm - 20 cm, a width within a range of 0.5 cm - 2.0 cm, and a thickness within a range of 0.05 cm - 0.5 cm, and the thicknesses of the stabilizing surface and the first and second grip surfaces (8, 10) are within a range of 0.05 cm - 0.2 cm, wherein the thickness of the support element is greater than the thickness of the stabilizing surface and of the first and second grip surfaces (8, 10); and the support element on the second longitudinal side between the second grip surface and the second fastening element has a lug, which is arranged adjacent to the second fastening element and which is set up in such a way that it extends essentially perpendicular to the second grip surface in the set-up state on the bow or extends at an angle (α) between 110° and 150° to the second grip surface. an oblong support element, which has been adapted to lie on a grip end of the bow stick, and which essentially has the shape of an arc when viewed in the longitudinal direction;
