Since the discovery of a fragmented Ice Age wind instrument was made in 1994 at a base camp of Palaeolithic reindeer hunters in Grubgraben/Kammern in Lower Austria, several attempts to reconstruct the instrument have been made. Due to the fact that both ends of the bone are broken pre-depositionally, varying options for reconstruction have been discussed since 1997. The most prominent research questions remain: How was the instrument likely played, how did it sound, and how can the sonic results of reconstruction experiments be displayed and interpreted? This paper will build a bridge from the first detailed research, carried out in the late nineties, to today’s more wide-spread field of scientific research on Palaeolithic aerophones, in order to shift attention to possibilities for reconstructing the Grubgraben artefact beyond those first attempts. It will also contextualize the instrument within recent music archaeological research and data. Throughout this paper, the main focus will be on studies of the instrument as an end-blown flute and the resulting tonal properties and pitch ranges, as they were presented and discussed at the 11th Symposium of the International Study Group on Music Archaeology in Berlin in November 2021 by Maria Hackl and Veronika Kaudela.
