Rüdinger was a student of Max Reger and worked from 1928 as a professor at the Musikhochschule in Munich. First printed in 1933, these important trio studies are intended for advanced students. They are based on themes in the works of Pachelbel, Krebs, Bach and Reger and are also well suited for performances.
