The violinist Daniel Auner has been performing on the world's stages for many years and is now one of the most sought-after Viennese violinists of his generation. The "master violinist" (Die Presse) and winner of the KlassikPreis Österreich, Eugéne Ysaÿe competition and winners of other international violin competitions is a guest of renowned orchestras and important music festivals around the world; often also as the first violinist of his string quartet, the Auner Quartet. The international press writes about his game: "... maneuverability, ease, definitely in the sense of capricious Vienneseism, but on the basis of a mentally and technically structured, i.e. the text and the very responsible acting attitude in the given atmosphere (klassik.com) … Playing with a light touch and an engaging tone, with nicely judged vibrato giving genial warmth (The Strad) . He is able to “give his interpretations of works from different eras an always captivating authenticity through his impressive sense of style, musical flexibility and intelligence “ (Radio Ö1 ). 
This ability is fed by Auner's musical curiosity, which even during his violin studies in Vienna regularly took him to the National Library and the Mozarteum Foundation in Salzburg in order to question the genesis and interpretation history of his repertoire and to deal with it meticulously. As a former student of Christian Altenburger, Igor Ozim and Boris Kuschnir, he has been working with the musicologist Dagmar Glüxam on the theory of affect in the 17th and 18th centuries, especially in recent years. Learning the rhetorical rules from Bach to Brahms as well as rediscovered performance methods led to a complete recording of the sonatas and partitas by Johann Sebastian Bach in 2019. The production supported by the University Mozarteum Salzburg as a research project with a revolutionary different approach, namely based on the rules of musical rhetoric, will appear in 2022 at ARS Produktion.
