She studied classical piano and later – with Beat Furrer – composition at the University of Music and Performing Arts, Graz. As an improviser she works within an electro-acoustic inspired sound-world, using specific preparations and extended techniques while pushing the limitations of the piano. Her performances draw from physicality and introspection, intuitive playing and high precision.

Harnik´s unique approach to her instrument as well as to improvisation and composition has led to many concert invitations. She is a member of numerous ensembles for improvised music and has performed and recorded with a number of internationally recognized representatives of the contemporary jazz scene in Europe and abroad. She writes commissioned works in addition to her concert activities, and her compositions are performed regularly at concerts and festivals for new music.
