This Dyson-Schwinger equation (DSE) aperçu 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, emphasising the importance of both scalar and axial-vector diquark correlations, and reporting the calculation of μnG n E(Q )/GM(Q ). The value of respecting symmetries, including Poincaré covariance, is stressed.
