  We study the decay process of large-spin mesons in the context of the
gauge/string duality, using generic properties of confining backgrounds and
systems with flavour branes. In the string picture, meson decay corresponds to
the quantum-mechanical process in which a string rotating on the IR "wall"
fluctuates, touches a flavour brane and splits into two smaller strings. This
process automatically encodes flavour conservation as well as the Zweig rule.
We show that the decay width computed in the string picture is in remarkable
agreement with the decay width obtained using the phenomenological Lund model.
