We discuss the two and three particle light-cone distribution amplitudes(DAs) of pseudoscalar nonsinglet mesons of twist 3 and 4. Using nonlocaloperator identities and conformal expansion, we derive closed expressions forseveral DAs. We also include meson-mass corrections which prove to be dominantin the twist 4 DAs of K and eta mesons. Explicit parametrizations for the DAsof pi, K and eta mesons are given, with the numerical input parametersdetermined from QCD sum rules.Comment: 18 pages Latex plus two postscript figures; JHEP package require
