Polymorphia

Polymorphia (Many forms) is a composition for 48 string instruments (24 violins and 8 each of violas, cellos and basses) composed by the Polish composer Krzysztof Penderecki in 1961. The piece was commissioned by the North German Radio Hamburg. It premiered on 16 April 1962 by the radio orchestra and was conducted by Andrzej Markowski. Polymorphia is dedicated to Hermann Moeck, the first of Penderecki’s editors in the West.

At the end of the 1950s and in the early 1960s, in Penderecki's post student years, he sought out new sonic and technical possibilities of instruments, particularly for strings, by unconventional means of articulation and peculiar treatment of sound-pitch. In doing so, Penderecki abandoned the traditional notation system and invented his own graphic notation, which was inspired by electroencephalograms. His earlier composition, Threnody to the Victims of Hiroshima (1960), received the first success of this type of work. Polymorphia was composed soon afterward as a result of his continuation with such experimental innovation.
