An alternative to the standard cold dark matter model has been recently proposed in which a significant fraction of the energy density of the universe is due to a dynamical scalar field (Formula presented) whose effective equation of state differs from that of matter, radiation or cosmological constant (Formula presented) In this paper, we determine how the (Formula presented) component modifies the primordial inflation gravitational wave (tensor metric) contribution to the cosmic microwave background anisotropy and, thereby, one of the key tests of inflation.
