In this thesis, I have investigated how to work creatively with melodies in the process of composing music. The starting point of the project was to transcribe phrases from different solos and to be assigned with newly composed ones from musicians around me. The melodies were applied to different composing methods. The methods were there to have a way of making music of the melodies and to put them in a context. The purpose of the work was to investigate how the use of these melodies and melody-based methods were affecting my composing. How could I create new musical possibilities in my composing by working like this? How could I in the process use the knowledge to develop harmonic possibilities and concepts on my main instrument? The work resulted in four newly composed pieces and concepts in how to improvise with melodies. I made the conclusions that the combination of variation, patience and a non-valuable working environment was a fruitful way to stay inspirated and creative.
