Tone-melody matching has been a subject of great interest in the field of linguistics. Generally speaking, music in tone languages takes both linguistic pitch and melodic pitch into account, and attempts to match the direction of movement of the two. A yet understudied area, however, has been tone-melody matching in languages experiencing tonogenesis. Seoul Korean is one such language, where aspirated and plain voiceless stops are merging in terms of VOT, and difference in F0 is taking its place as the distinguishing feature. This study explores whether similar tone-melody matching patterns appear in the music of an emerging tone language as does in that of an established tone language. 1092 bigrams from nine K-Pop songs released in the last five years were analyzed, and no clear effect was observed, suggesting the Seoul Korean tonogenetic shift is not yet complete, or that it has not extended to K-Pop music. However, the study brought to light many intriguing questions which present opportunities for future research.

Occitan, a Gallo-Romance language spoken in the South of France, exists at an interesting nexus – it has been documented since the Middle Ages to exhibit polymorphy, the free variation of forms with identical semantic and pragmatic value, and also has been undergoing language attrition for centuries. Current literature has suggested that Occitan verbal polymorphy, in which up to four paradigms for a given verb can exist in free variation, has phonological roots and cannot be correlated with attrition at all, a surprising result given that attrition has infiltrated almost every aspect of Occitan grammar. Much of the polymorphy presented in the literature, however, cannot be explained solely through phonology, necessitating a morphological analysis. This thesis presents a novel analysis of Occitan verbal morphology and polymorphy through a Distributed Morphology framework, first analyzing verbs in the standard dialect and then extending into polymorphic paradigms. In addition to elucidating the vocabulary items and underlying rules governing standard verbal morphology, this analysis yields seven morphological processes that generate polymorphism in Occitan, all of which are correlated to language attrition patterns. While this does not imply that polymorphy and language decay are inherently linked in all circumstances, it indicates that Occitan morphology and grammar cannot be extricated from its sociolinguistic situation, suggesting future avenues for research in attrition, polymorphy, and minority languages.
