Beate Müller, born in Erfurt, began playing the violin at the age of 8. She attended the Special School of Music in Weimar and switched to the viola a year before she began her studies. She first studied with Thomas Wünsch in Weimar and later with Dietmar Hallmann in Leipzig.
In 1993 she received the scholarship award from RWE Essen. She gained orchestral experience as a substitute at the Leipzig Gewandhaus.
While still a student, she earned her orchestral position with the Dresden Philharmonic.
She graduated with distinction. In addition to her work as an orchestral musician, she has been playing quartet in permanent ensembles, regularly in the chamber orchestra of the Philharmonie, and chamber music elsewhere.
She plays a viola made by Bernd Hiller.
