Georg Friedrich Haas, who was born in Graz and has risen to become one of the most important Austrian composers internationally, felt limited by the established system of equal temperament. Notes shaded by microtonal deviations have therefore been determining factors in his compositions since the beginning of his career. Intensive experimentation with overtones has lent a new quality of radicalism to Haas’s sound and, as a result, his works make particularly high demands on their performers. Hass studied at the Musikhochschule in Graz and with Friedrich Cerha at the Hochschule für Musik in Vienna, and has both attended and lectured at the Darmstadt Summer Courses. In the 1980s and 1990s, he participated in IRCAM and was awarded a fellowship for the Salzuburg Festival, as well as the Sandoz Prize and the Young Composers Grants of the Federal Ministry for Science, Research, and Culture. More recent awards include an International Rostrum of Composers prize for his Violin Concerto, a City of Vienna Prize for Music, the Andrzej Dobrowolski Composition Award, and the Großer Österreichischer Staatspreis award of Austria. He has also lectured at the Music Academy of the City of Basel, Switzerland and was a featured composer at both the Klangspuren Festival in Austria and the Borealis Festival in Norway.
