Wolfgang Niessner has coached me extensively as part of my first opera projects, from which I benefit very much today.
Not only his profound introduction to conducting technique, but also his extensive knowledge about composition, style, formal layout and dramaturgy of a work, stylistical playing of basso continuo, timbres and their balance – all in the service of the affect and inspired by his longstanding cooperation with Nikolaus Harnoncourt – gave me the necessary basis for the musical work in the field of opera.
