Tagba Tone: a case of tier hierarchization

Tagba (Senufo) is a tone language that presents tonal patterns that appear quite regular at first glance. However, these are difficult to model under standard autosegmental hierarchical assumptions regarding the placement of skeleton, segments and tones. In this paper, we will present Tagba tonology and demonstrate that it can be accounted for by readjusting the tiers of hierarchization. From this, we reason that the proposed hierarchy is parametric and language specific.
