This Action (WoodMusICK - WOODen MUSical Instrument Conservation and Knowledge) aims to combine forces and to foster research on wooden musical instruments in order to preserve and develop the dissemination of knowledge on musical instruments in Europe through inter disciplinary research. This program involves curators and conservators on the one side, wood scientists, chemists and acousticians on the other side, and finally, researchers in organology and making of instruments. As part of the CIMCIM (International Committee of Musical Instrument Museums and Collections) network, working with some members of the former WoodCultHer COST and with makers, the project will integrate study, conservation and preservation works on musical instruments in heritage, and will allow the different European teams working on wood to participate in research projects on musical instruments. The collaboration will help to develop cooperative programs on specific projects about the study and identification of artefacts and about the conservation of musical instruments. The main objective of this COST Action will be to improve the conservation of our wooden musical instruments heritage by increasing interaction and synergy between wood scientists and other professionals (including instrument makers) applying wood science, curator, organologists and makers towards the study, conservation and restoration of wooden instrument collections of artistic or historic interest, and to offer a novel and reliable, independent and global knowledge on these collections.
