Reconsidering tone and melodies in Kikamba
The melodic tone system of Kikamba, as described by Roberts-Kohno (2000; 2014),
stands out as particularly complex within the context of recent crosslinguistic
work on melodic tone in Bantu (Odden & Bickmore 2014; Bickmore 2015). It is
unique, for example, in possessing a melody that assigns four distinct tones to
three stem-internal positions simultaneously. The apparent existence of such com-
plex melodies raises doubts as to whether there are any substantive restrictions
on the possible form of a tonal melody. We argue, however, that these doubts are
premature. We propose a new analysis of Kikamba in which (a) melodies refer
to no more than two target positions at a time and (b) melodies target only two
possible stem-internal positions, each of which occurs commonly within Bantu
melodic tone systems. This simplification is achieved by (a) rejecting the existence
of a melodic L tone assigned to the penult, and attributing its putative effects to in-
teractions among other, more basic tones, and (b) distinguishing between melodic
tones assigned early in the phonological derivation and other suffixal tones added
later. In general, we argue that since core properties of melodic tone are often
obscured in surface forms due to interactions with language-particular rules, the
crosslinguistic comparison of melodic tone should proceed on the basis of a (more)
underlying level in which these rules are controlled for. Once this is done, the ex-
ceptional properties of Kikamba melodic tone largely disappear.
