Claire Genewein was born in Munich, Germany. She completed her first studies on flute cum laude at the Mozarteum in Salzburg, soon thereafter attaining her concert degree under Philippe Racine at the Zurich University of The Arts. This was followed by further degrees in baroque flute, first one in early music with a major in baroque flute from the Schola Cantorum Basiliensis and an M.A. from the Royal Conservatory in The Hague, Netherlands, under Barthold Kuijken.
Having completed the coursework of the «Performing and Creative Arts» program at the Orpheus Institute in Ghent, Belgium, she finished her doctoral dissertation on The performance practice of Italian instrumental music in relation to vocal music and text: Sources and their modern realization at the University of Leiden (NL) in 2014. As part of her doctoral research, she - together with Andrea Marcon - was able to reconstruct Baldasare Galuppi’s incomplete opera L’Olimpiade. Subsequently, the opera was performed by the Teatro Malibran in Venice in 2006 (L'Olimpiade DVD, Dynamik 2009).
Claire Genewein was the recipient of a special award from Karlheinz Stockhausen for her interpretation of the composer’s famous Zungenspitzentanz for piccolo, and in 1998 she won second place at the International Piccolo Competition in Phoenix, USA. In 2000, together with the anthos percussion ensemble she won first place for her interpretation of Kathinkas Gesang, also by Stockhausen, followed by a second place at the 2004 baroque flute competition of the National Flute Organisation (USA).
