Music is a part of everyday life for every human being. Traditional music, especially music that accompanies traditional dances, is a part of a culture that has lost its closeness to student life. Whereas traditional music contains many interesting concepts of knowledge to be used as the basis for learning. Gandrung Jejer Jaran Dawuk (GJJD) dance is one of the traditional dances from Indonesia which contains various concepts of knowledge. The accompanying music also contains many concepts of knowledge, particularly geometry. Geometry is one of the concepts in mathematics that is difficult for students to understand at elementary, secondary, and higher levels without visual objects. Geometric concepts can be explored from the musical accompaniment of the GJJD dance, such as two-dimensional shapes (rectangles, trapezoids, circles, semicircles, and triangles), three-dimensional shapes (prisms, beheaded prisms, and beheaded cones), parallel and intersecting lines, similarity, and fractal geometry. The exploration of the musical accompaniment of the GJJD dance shows that musical instruments and their notations can become interesting visual objects in learning mathematics, especially in the concept of geometry. Geometric concepts that have been explored still require further processing to be part of learning in schools in various forms such as teaching materials or learning media. © 2023 Author(s).
