In The Mix: Hip Hop's Impact On Genre Development And Cultural Influence In African And Jamaican Music, Kinzi Kabadeh Dec 2024

In The Mix: Hip Hop's Impact On Genre Development And Cultural Influence In African And Jamaican Music, Kinzi Kabadeh

Postgraduate

In this exegesis, I contend that certain compositional elements and production methods of dancehall, amapiano, and afrobeats demonstrate hip hop’s influence on contemporary Jamaican and African electronic music. In particular, the drum programming, track mixing, and use of sampling demonstrate a cross-pollination and cultural transfer between the two forms of music (on one hand, the African and Jamaican genres of dancehall, amapiano, and afrobeats, and on the other, the African American music of hip hop). These genres are fundamental to contemporary Black culture and share origins as vehicles for resistance to oppressive forces.


“The Wonderful Improvement”: Landscape And Morals In Jane Austen’S Mansfield Park, Montanah Middleton Dec 2024

“The Wonderful Improvement”: Landscape And Morals In Jane Austen’S Mansfield Park, Montanah Middleton

Honors Theses

A Rose By Any Other Name: Impressionism As Definition And Aesthetic In The Music Of Claude Debussy, Erin Smith Dec 2024

A Rose By Any Other Name: Impressionism As Definition And Aesthetic In The Music Of Claude Debussy, Erin Smith

Honors Theses

The premiere of Parisian composer Claude Debussy’s Prélude à l’après-midi d’un faune created a link between his music and the artistic Impressionism movement, which began in 1874 as a rejection of Realism. Musical Impressionism, initially an ill-fitting title, would gradually shift to encompass the compositional techniques of Debussy, and would also inspire new musical styles as a rejection of musical Impressionism. This project compares the defining features of Impressionism across artistic mediums, analyzes Debussy's music in relation to Impressionist painting, and examines his resistance to the label within a broader dialogue on evoking sensation through abstract forms. In doing so, …
