In this project, I explore how we can deepen our understanding of improvisation by applying theories, concepts and structures from verbal interaction. I used four different exercises for working on this with my group. In addition to this, I also composed five new pieces of music in which we could apply these new concepts. In the composition process I transcribed real life conversations, and used elements like rhythm, pitch, and pacing from the speech as a foundation for the music. Throughout the study I make comparisons between musical and verbal interaction and explore similarities and differences between the two modes of interaction. I look at the topic from both a linguist and musician’s perspective, using the works of linguist Stina Eriksson, musicologist David Borgo, and writer/musician Stephen Nachmanovitch as sources.  The text follows the process from breaking down aspects of interaction, describing the work with the exercises, and the finished songs which were performed in my bachelor’s recital. At the end I reflect upon the different outcomes of the practice methods we used, and why studying verbal interaction might be a relevant technique in working with co-playing in an ensemble. The paper results in new ways to work with musical co-play with the based on verbal interaction and how we can bring out the essence of a song.
