The Misa Sine Nomine is a 1977 musical work for narrator, mixed choirs with up to 36 voices, organ, and percussion by Leon Schidlowsky. It was composed in memory of Chilean folk singer and human rights activist Víctor Jara. The work is a setting of parts of the mass ordinary juxtaposed with Biblical passages in Hebrew, and texts in other languages by various contemporary authors, including by the composer himself. The composition is in eleven movements and utilizes different groupings of performers in each. The score uses graphic notation. The movements, which can be performed separately, are meant to be accompanied by visual projections. It was first performed in Hamburg in 1980.
