A striking feature of the strong interaction is its emergent 1-GeV mass-scale, as exhibited in the masses of protons and neutrons and numerous other hadronic bound states. In sharp contrast, the energy needed to hold the gluons and quarks within the Nambu-Goldstone Bosons, such as the pion and kaon, is not so readily apparent. Even if both quarks and gluons acquire mass dynamically, in all hadrons, the pion ends up near-massless, and the kaon ends up acquiring just half the 1-GeV mass scale. A coherent effort in QCD phenomenology and continuum calculations, in exa-scale computing as provided by Lattice QCD, and in experiments are required to make progress in understanding the origins of these disparate masses and the distribution of that mass within them. In this talk we will discuss measurements of meson structure, which serve as a laboratory to elucidate fundamental aspects of QCD, fit in with ongoing and foreseen programs efforts worldwide.
