In a 2011 article, Matija Turk published the results of a collaboration with Ljuben Dimkaroski, an academic musician who had made replicas of the artifact. The authors argue that the instrument encompassed a range of two and a half octaves, which can be extended to three octaves by overblowing. Dimkaroski created over 30 wooden and bone replicas of the flute and experimented with them. The replicas were made from femurs of juvenile brown bears provided by the Hunters Association of Slovenia, but also calf, goat, pig, roe and red deer bones. In the end, he concentrated on playing a replica made on a femur of a juvenile cave bear from Divje Babe I Cave, to come as close as possible to the dimensions of the original.
