Limitations of present knowledge of plasma equilibrium profiles hamper
a proper identification of MHD modes. However, through continued impr
ovement of both numerical calculations and experimental observations w
e may witness the birth of a new kind of spectroscopy, properly called
MHD spectroscopy, in the coming decade. This is illustrated by studie
s of Edge Localised Modes and external excitation of Toroidal Alfven E
igenmodes.
