This study aims to explore the defining characteristics of jazz dance as a genre with the ambition of reaching a deeper understanding of the art form as well as clarifying the foundations for my own jazz dance teaching. Using a qualitative research method, the study examines the perceptions of four dance educators, each with experience in dancing and teaching different forms of jazz. Drawing on a phenomenographic perspective, the study identifies variations in perceptions through semi-structured interviews and categorization. The findings present six descriptive categories of important components within jazz dance including Body and Music Interplay, Relevant Music Choices, Freedom, Play and Individuality, Contrasting Dynamics, Technical Finesse and Body Control, and Interaction and Expression. Furthermore, the study discusses the challenges of defining jazz dance but highlights the significance of embodied musicality and Africanist aesthetics as key elements of the art form, as well as emphasizing the concept of "swing" as central to jazz and the perception of “jazziness”. In conclusion the study shows a broad variety in perceptions which contribute to an increased awareness and understanding of jazz dance as well as providing tools for communication in jazz dance teaching. Ultimately the study encourages further research on the topic.
