This paper develops an Optimality Theoretic analysis of Cupeno accent.
 This analysis crucially depends on underlying specifications of prosody
 and constraints on faithfulness to underlying prosody.  Input-Output
 prosodic faithfulness is necessary in accounting for distinctive stress
 in the inventory of accentual patterns observed in roots.  Prosodic
 faithfulness is equally important in explaining the observation that
 root stress overrides affix stress; in fact, this observation is
 accounted for as a special case of the crosslinguistic tendency for
 roots to license a wider range of contrasts than affixes, an
 explanation that is not available to plausible alternatives.
 Finally, faithfulness to underlying prosody is shown to be crucial
 in describing a pattern of unbounded stress, essentially characterizing
 the intrinsic prominence of underlying accent.
