  This work aims to improve our understanding of the resonance wood and to
investigate the interactions between their physical-mechanical properties,
natural variability, and the violin makers' ways of choosing their materials.
In order to identify the luthiers' practices and opinions, a socio-technical
survey was conducted. Physical, vibrational, and visual/structural
characteristics of the resonance wood obtained from several provenances with a
variety of quality grades were also determined. Finally, these two approaches
were completed by a psychosensory evaluation to compare the measurements that
we have conducted with the perception and qualification of wood by the violin
makers.
