  We analyze some aspects of the perturbative and non-perturbative interactions
in the composition of heavy quarkonia, heavy and light baryons ($ccc$ and $uuu$
ones), as well as all charm tetraquarks ($cc\bar c\bar c$). Using the
hyper-spherical approximation and effective radial potentials (in 6 and 9
dimensions, respectively) we derive their spectra and wave functions. In all of
the cases, we focus on the splittings between the s-shell levels, which are
remarkably insensitive to the quark masses, but proportional to the effective
interaction potentials. We use the traditional Cornell-like potentials, and the
non-perturbative instanton-induced static potentials, from correlators of two,
three and four Wilson lines, and find rather satisfactory description of
spectra in all cases.
