This thesis discloses my exploration of non-isochronous meters through composition and practice. During my two-year studies at the Royal College of Music in Stockholm, I explored different unevenly divided time signatures by practicing them in various ways, producing transcriptions, compositions and arrangements.The main purpose of this project was to further my knowledge and skills within these time signatures and thereby expand my horizon on perceiving, conceptualizing, composing and playing them. My endeavors culminated in seven original compositions, arranged for a jazz sextet, which I rehearsed and performed with an ensemble. During the process of composing, arranging, practicing and rehearsing, I gained a lot of articulated knowledge as well as embodied knowledge of the idiosyncrasies of various non-isochronous meters and different ways to perceive and play them.
