Abstract
When modelling woodwinds, when one try to built synthetic reeds one need a good mechanical description of the cane reed. We show that the basic approach in terms of a simple mechanical oscillator is not valid. The correct description must include a viscoplastic characteristic for a wet reed and a viscoelastic one for the dry reed. So it is not possible with classic methods to determine the elastic modulus of a cane reed, and the physical models which include the reed behaviour with a modal description should have to be modify according the equations we present here.
