  We analyze the (1+1) dimensional QCD (QCD_2) at finite density to consider a
number of qualitative issues: confinement in dense quark matter, the chiral
symmetry breaking near the Fermi surface, the relation between chiral spirals
and quark number density, and a possibility of the spontaneous flavor symmetry
breaking. We argue that while the free energy is dominated by perturbative
quarks, confined excitations at zero density can persist up to high density. So
quark matter in QCD$_2$ is an example of Quarkyonic matter. The non-Abelian
bosonization and associated charge-flavor-color separation are mainly used in
order to clarify basic structures of QCD_2 at finite density.
