Emanations, also referred to by its original German title Emanationen or by its Polish title Emanacje, is a composition for two orchestras by Polish composer Krzysztof Penderecki.
It would eventually be premiered on September 7, 1961, at the Darmstadt International Summer Courses for New Music.
Michael Gielen conducted the Southwest German Radio Symphony Orchestra for its premiere.
[1] Emanations is scored for two string orchestras that are tuned a minor second apart.
It takes approximately 7 minutes to perform and features the sound-painting compositional style that became a well-known trait of his works from the 60s and 70s, until his first symphony.
