  In this review paper, we summarise the goals of asteroseismic studies of
close binary stars. We first briefly recall the basic principles of
asteroseismology, and highlight how the binarity of a star can be an asset, but
also a complication, for the interpretation of the stellar oscillations. We
discuss a few sample studies of pulsations in close binaries and summarise some
case studies. This leads us to conclude that asteroseismology of close binaries
is a challenging field of research, but with large potential for the
improvement of current stellar structure theory. Finally, we highlight the best
observing strategy to make efficient progress in the near future.
