  We consider a model of dynamical electroweak symmetry breaking with a
partially composite Goldstone Higgs. The model is based on a
strongly-interacting fermionic sector coupled to a fundamental scalar sector
via Yukawa interactions. The SU(4) x SU(4) global symmetry of these two sectors
is broken to a single SU(4) via Yukawa interactions. Electroweak symmetry
breaking is dynamically induced by condensation due to the strong interactions
in the new fermionic sector which further breaks the global symmetry SU(4) to
Sp(4). The Higgs boson arises as a partially composite state which is an exact
Goldstone boson in the limit where SM interactions are turned off. Terms
breaking the SU(4) global symmetry explicitly generate a mass for the Goldstone
Higgs. The model realizes in different limits both (partially) composite Higgs
and (bosonic) Technicolor models, thereby providing a convenient unified
framework for phenomenological studies of composite dynamics. It is also a
dynamical extension of the recent elementary Goldstone-Higgs model.
