In this thesis I try to find ways to be more independent and conscious in my interpretation of the music which I am playing. To be able to be more sure of myself and my own decisions I try to find methods on how to achieve this. The methods includes reading articles about interpretation, interviewing musicians and interpret and perform music. The pieces I have chosen are a solosuite by Max Reger, a concerto by Georg Philipp Telemann and a clarinet sonata by Johannes Brahms. I made some concerts where I try to achieve my goals.
