The FEM model of a violin resonance body presented in the article has been developed in order to simulate various issues in the field of violin dynamics and vibro-acoustics. All violin parts participating in the vibrations of the resonance body (solid and shell parts) are included in the model. Material properties and material orientation (anisotropy) of wood species used to make the violin parts have been taken into account in the model. Properties of spruce have been applied to the top plate (with f-holes) and solid parts. Properties of maple have been applied to the back plate, ribs and bridge. Two basic problems were considered: simulation and analysis of violin body vibrations in the cases of natural vibrations (*Frequency) and forced vibrations - excided by strings (*Steady-state dynamics). The results of simulations have been described and illustrated.
