Ihanzu possesses two phonemic tone contrasts: low (zero) and high. This talk, incorporating audio recordings from recent fieldwork, explores and demonstrates the layers of rules which dictate the instantiation of tone in this language. Note: This talk has not gone through a process of peer review, and findings should therefore be treated as preliminary and subject to change.
