This Dyson-Schwinger equation (DSE) apercu highlights recent applications to mesons. It reports features of, and results for, pseudoscalar and scalar bound-state residues in vacuum polarisations, and exhibits how a restoration of chiral symmetry in meson trajectories could be manifest in a relationship between them. It also touches on nucleon studies, emphasizing the importance of both scalar and axial-vector diquark correlations, and reporting the calculation of {mu}{sub n} G{sub E}{sup n}(Q{sup 2})/G{sub M}{sup n}(Q{sup 2}). The value of respecting symmetries, including Poincare covariance, is stressed.
