The main purpose of the essay is to serve as a documentation of my research practice on the movement of the tailbone and its connections to my dancing body. The essay is being written from my personal perspective which springs out of my interest in the importance of using the tailbone whilst dancing. In the first part of the text I have included personal information to the reader about where my interest in the movement of the tailbone arose. One of the methods during the research was to write a process diary as a way to combine a physical practice and writing practice. This process diary is now a big part of this essay. In the essay you as a redear can follow how the research has transformed and changed throughout working time on the project. The second part of the essay reflects on the process of researching the tailbone-ing movement practice and what the practical presentation should look like. In the last pages of the essay you find a choreographic score which is both a documentation of the practice as well as a score to perform it. Working on the essay opens up new possibilties for further research on the importance of the tailbone and the pelvic floor in the dancing body. / <p>This master work includes both a performing and a written part. </p>
