I shall briefly review the salient features of target space duality (T-duality) and recall some essential results. I shall outline a prescription to derive the S-matrix for the scattering of massless stringy states that arise in the compactification of closed bosonic strings on a torus at the tree level. It will be shown that the S-matrix elements can be expressed in a T-duality invariant form. The Kawai-Lewellen-Tye formalism plays an important role in our approach.
