  After noting the well known similarity of the minimal electro-weak Higgs
sector with the linear sigma model for the pion and the sigma, it is found that
a small mixing term between the two models generates a pion mass. Although the
custodial SU(2)L x SU(2)R, and the gauged SU(2)L x U(1) symmetry for the whole
model remains intact, the mixing breaks the relative chiral symmetry between
the two sectors. The mixing should be calculable from light quark masses as a
quantum correction. This simple mechanism of "relative symmetry breaking" is
believed to have applications for other forms of symmetry breaking.
