According to the P-Map, a phonological mapping is less faithful to the extent that there is more perceptual distance between its input and output. Although this idea is attractive, it cannot be implemented in the standard parallel version of Optimality Theory. This note explains why and shows how a derivational version of OT, Harmonic Serialism, can solve this problem.
