He was the son of Fran and Alojzija Cvetko, both schoolteachers in Vučja Vas, and the older brother of the composer Ciril Cvetko. He studied at the Faculty of Arts at the University of Ljubljana and at the Ljubljana Conservatory, and continued his education in composition in Prague. He received his doctorate in 1938 with the dissertation Problem občega muzikalnega vzgajanja ter izobraževanja.

From 1962 to 1981 he was a professor of the history of Slovenian and modern world music and the head of the Department of Musicology at the University of Ljubljana's Faculty of Arts. He served as the dean of the Faculty of Arts from 1970 to 1972. In 1982 the University of Ljubljana awarded him the title of distinguished professor.

He research initially focused on issues of music theory and education, but soon after 1945 he started focusing on music history. He engaged in extensive work based on critical study of sources and issues of musical style to create a solid basis for Slovenian music history, providing an impetus for similar work elsewhere in Yugoslavia. His critical editions of compositions are of exceptional importance; they were the first of their kind in Slovenia. He published numerous articles in Yugoslav and international periodicals. He participated in international musicological conferences and delivered talks at various universities and institutions, and also in radio broadcasts. The Department of Musicology was founded at the University of Ljubljana's Faculty of Arts in 1962 as a result of his efforts. In 1965 he started publishing the journal Muzikološki zbornik, which included contributions from Yugoslavia and abroad. In 1972 he founded the SAZU Institute of Musicology, which began operating in 1980. He died in Ljubljana at the age of 82 years. On 18 September 2011, a bust of him was unveiled in his native village of Vučja Vas.
