We study the most general, relativistic, constituent [ital q[bar q]] meson wave function within a new covariant framework. We find that by including a tensor wave function component, a pure valence quark model is now capable of reproducing not only all static pion data ([ital f][sub [pi]],[l angle][ital r][sub [pi]][sup 2][r angle]) but also the distribution amplitude, form factor [[ital F][sub [pi]]([ital Q][sup 2])], and structure functions. Further, our generalized spin wave function provides a much better detailed description of meson properties than models using a simple relativistic extension of the [ital S]=[ital L]=0 nonrelativistic wave function.
