Life Kozina was born to a musical family in Novo Mesto, then part of Austria-Hungary. In Ljubljana, Kozina began studying philosophy and mathematics and in the same time also piano and violin, but later completely turned to the study of music. He graduated from composition in Vienna in 1930, and completed the studies of conducting and composition also in Prague. After his return from Prague he worked for a short time (1932–34) at Ljubljana and Maribor Opera, and then worked at Maribor Music Society ().
