This article foregrounds imagination to consider how African diasporic conditions converge with choreographic expression. The analysis “un/maps” dominant understandings of the choreographic process of mid-twentieth-century African American choreographer-anthropologist Katherine Dunham by expanding Kamau E. Brathwaite's (1993) concept of Tidalectics beyond the Caribbean to the wider African diaspora and a distinctly Caribbean comprehension of diasporic imagination. Utilizing datasets and visualizations created by the project, Dunham's Data: Katherine Dunham and Digital Methods for Dance Historical Inquiry, this article traces how the concept of Brazil is imagined and reimagined within Dunham's archive from 1937 to 1962. In doing so, it considers the complex positionality of Dunham as both a pioneering minoritized woman navigating the politics of race, gender, and financial precarity, and someone who yielded their imperial privilege as a US citizen through their career to bring nuance to Dunham's narrative as a canonical dance figure.
