Since 1968, many clarinetists have learned to play their instrument by using Ewald Koch's "Schule für Klarinette". Many tips and suggestions received over the years have prompted the author and the publisher to produce a thorough revision, allowing the solid landmark work to continue setting standards also in the 21st century.
The method's stylistic spectrum is broad: next to classical and contemporary works, the volume also includes international folklore, including blues and spirituals, Klezmer and Latin music. The book has many duets, which make it particularly well suited to group instruction.

Koch presents a new selection of pieces for clarinet and piano in "Von leicht bis virtuos." The first volume contains the piano accompaniments to Volume I of the method. The second volume harmonizes completely with the Volume II of the Koch method (DV 30071), although the pieces can also be played and performed independently of the method.

„In der Neufassung des zu einem musikpädagogischen Markenzeichen gewordenen Lehrwerks bündeln sich gesammelte Erfahrungen einer international anerkannten Musiker- und Lehrerpersönlichkeit... Die kommende Generation der Klarinettenschüler ist zu beglückwünschen, wenn sie nach dieser Schule lernen darf." (Irene Krieger, rohrblatt)
