The algebraic content of chiral symmetry constrains the strong interactions of mesons containing a single heavy quark. We show that the S-wave single-pion transition amplitudes of all heavy meson states are determined as a consequence of the participation of these states in reducible multiplets of unbroken SU(2)L× SU(2)R. We find this representation content by making use of phenomenologically inspired Lie-algebraic sum rules, together with QCD constraints on the heavy meson spectrum in the heavy quark limit. For example, the transition amplitude for the process P^*→ Pπ, where P is a D or a B meson, is predicted to vanish. We also consider the Kaon system in light of our general conclusions for I=\oneh states.
