Khoisan tonology, specifically !Xoo tonology, has been argued to
have contour unit tones (Traill, 1985), but Haacke (1992) argues for
a decompositional approach to Khoekhoe. This paper gives evidence for a
decompositional approach for both Ju/'hoasi and !Xoo. The mora is the
tone bearing unit since the number of tones in a word is equal to the
number of moras. The domain of tonal specification is the morpheme.
There are restrictions that occur in this domain, but not in polymor-
phemic domains. Derived tonal sequences follow a stepwise pattern. A
scalar phonetically-based feature for tone is proposed to elucidate the
data, and an Optimality Theoretic analysis is given which allows the
differences between the two languages to be explained as a difference
in constraint ranking.
