The Collection — of Historic Musical Instruments (Kunsthistorisches Museum, Vienna) has gained extensive experience in 3D-CT-based inspection, rendering, visualization and measuring of unique, fragile items and museum exhibits due to two large research projects it has supervised since 2007. The project supported by the Austrian Science Fund (FWF) focussed on a broad group of Renaissance wind instruments (18 cometti, a serpent, six crumhorns and a wind cap shawm). The research objective was the exact calculation of all acoustical and structural parameters that are not accessible without using a 3D-CT non-destructing test procedure to enable realistic reproductions of the musical instruments by instrument makers. The other project, supported by the OeNB-Jubilaumsfonds, is stil in the implementation phase, and aims to document the conservational condition of precious violins and to demonstrate the contingent deformation of recently made violins" constructional parts within a long term playing. The present survey informs about the different high- technological devices used for the examination of historic musical instruments and reports on the research findings
