Alphabet - Krzysztof Penderecki
The sonorist technique depends on attaching the greatest importance in musical progressions to the qualities of sound. Though in principle most music written in the second half of the 20th century is characterised by an emancipation of sound, in Polish works of the 1960s, sound was treated in a highly specific manner. Polish sonoristic compositions contained a particular abundance of glissandi, clusters and sharp contrasts, as well as unconventional techniques of articulation and extended forms of expression achieved on traditional instruments. Penderecki’s early works are a pronounced manifestation of that technique.
