Recent high resolution observations from TRACE have demonstrated that oscillations in the corona can be observed from space. In this paper we consider the following question. What is the nature of these motions, and how can they be used to understand something about the corona? We briefly review some of the observational results, and discuss the interpretation of these results within the framework of MHD wave propagation and damping in coronal loops, open flux tubes, and loops with cusp structures. The prospect for future improvements in the theory and observations will be discussed.
