This paper attempts to describe various details of the tonal system of Hausa within the framework of generative phonology. Aspects of tone in Hausa are discussed under the following headings: low tone raising, low-high rule, falling tones and the evaluation measure, tone deletion, and derived nouns and adjectives. Where specific proposals are presented arguments are given which make explicit the author's reasons for believing that phonological theory must value these proposals more highly than conceivable alternatives. The author notes that for the purposes of the present paper the issue of rule ordering is largely ignored and "underlying forms" discussed are assumed to be as close to surface realizations as possible.
