Abstract This paper will present my master project which is a collaboration with the Israeli composer Matan Ben Zahav. The idea behind this work, came from my wish to widen the kind of contemporary repertoire I wish to play more of, these days and in the future. The pieces we dealt with in the project were a sonata for recorder and keyboard and a recorder trio that Ben Zahav composed. The trio was composed before the idea for the project was fully formed and helped me think of the idea for the project. After forming an idea, I asked Ben Zahav if he was willing to compose a sonata and that's how the project started. I decided that I would investigate the process and product of a collaborative work with Ben Zahav on the sonata for recorder and keyboard and recorder trio. The collaboration started during rehearsals in which we explored the new repertoire both musically and technically, we suggested different options and tried to make the pieces as comfortable for the recorder as we could. This exploration revealed the different opportunities and benefits that a collaboration can bring.
