This thesis examines selected musical compositions of Pete Seeger through the lens of his musical education and his life experiences and how those influenced his creative output.Drawing on his vast knowledge of the folk music tradition, Seeger crafted songs that gave voice to his own personal sociopolitical philosophy, which often found expression in political activism. The body of the thesis comprises three case studies, each of which provides an analysis of three paradigmatic songs that explore Seeger’s creative compositional processes and musical influences, his deeply held anti-war stance, and his efforts on behalf of the environment.
