Papageorgiou’s music has always had a certain predilection towards various forms of similarity and structural reiteration. In such a context, structural redundancy and parsimony stand at the epicenter of his work, as recurrences of patterns that share the same underlying structure unfold in time, elaborating centripetally on the same structural complex or similar structural features again and again, creating, maintaining and exalting one or various states from a single or from a variety of perspectives. Dimitri majored in composition with Hermann Markus Pressl and Andreij Dobrowolski at the University of Music and Dramatic Arts at Graz in Austria. From 1998-2002 he held a Presidential Fellowship of the University of Iowa, U.S.A., for a Ph.D. in Composition with Donald Martin Jenni, Jeremy Dale Roberts, and David Karl Gompper. Since 2007, he is appointed as assistant professor of composition at the Department of Music Studies of the Aristotle University of Thessaloniki.
