  Spontaneous breaking of chiral symmetry is discussed in the light-cone
framework. The essential ingredient is an infinite number of constituents near
zero light-cone momentum. These high (light-cone) energy degrees of freedom
freeze out and leave behind some explicit symmetry breaking in the low
(light-cone) energy effective Hamiltonian. Connections with Regge theory and
soft pion theorems are discussed. Taking the order parameter to be the 4-th
component of a chiral 4-vector, the effect of the spontaneous symmetry breaking
on meson masses and decay width is calculated and compared with experimental
data.
