Annette Geiger took all that she learned about violin playing and transferred it over to the viola in order to play chamber music with her family. Fascinated by the register and sound of the instrument, she soon started to play viola in various youth orchestras. After a concert of the Cherubini quartet, she decided to dedicate her studies to the viola, studying with Hariolf Schlichtig and Kim Kashkashian in Munich as well as Thomas Riebl at the Mozarteum in Salzburg. She also participated in numerous master classes, studying with Tabea Zimmermann and Vladimir Mendelssohn in chamber music festivals as well as with Sandor Vegh in Prussia Cove.
