Universe Symphony is the 3rd orchestral concert work by the Turkish composer Fazıl Say. Universe Symphony's world premiere took place in Salzburg Festival on 7 October 2012.
Universe Symphony is based on astronomy research that is variable and parallel to the changes in science. Fazıl Say's work evolved out of data collected in 2012 in this field of study. In this respect, The Big Bang, expansion of the universe, and Gliese 581 g’s Earth-like appearance means finding the ‘God particle’ in dark matter may not be a fact for the modern age of science. As a result, the composer evolved his work out of today's data[1] to create a fictional story. The following Movements describe a blend of that research and Fazil Say's inspiration for composing his Universe Symphony.
