Leopold Brauneiss, (b. 1961) is an Austrian composer, musicologist and teacher, based in Vienna. He studied at the University of Vienna (musicology) and the University of Music and Performing Arts (music education, piano, composition with Heinz Kratochwl) and received his doctorate in music in 1988. From 1990 to 2010 he has thought music theory at the J.M.-Hauer conservatory Wiener Neustadt, since 2004 he has been lecturer for harmony and counterpoint at the University of Vienna, since 2006 he has held a lectureship in harmony, counterpoint and instrumentation at the Hochschule für Musik und Theater „Felix Mendelssohn Bartholdy“ Leipzig, The main field of his musicological research is the so called Tintinnabuly  Style of Arvo Pärt, whom he has known personally for over 20 years. The style's characteristic aesthetics of reduction as well as the simple yet strict structural of its composition techniqes has influenced his music to a great extent. He tries, however, to enrich it someitmes by adding chromatic or even dodecaphonic elements within the tonal frame.  His works have been performed by renowed artists such as Gidon Kremer, ensembles like Kremerata baltica and orchestras like Tonkuenstlerorchester Niederoesterreich and have been presented at prestiguos festivals like Wien Modern and Kammermusikfestival Lockenhaus.
