Czerny has been underestimated as a composer of studies for a long time. In the meantime, however, his studies are used more and more in lessons because he is a real master in tackling technical and musical problems in concise exercises. Against the background of the discussion about practising ("Wie übe ich effektiv und zielorientiert?"/How to practise in an efficient and targeted manner), Czerny's studies have gained in importance. As a consequence, Schott has included the well-known cycle "100 leichte Übungsstücke op. 139" in its study series 'Essential Exercises', with fingerings and didactic information by Wilhelm Ohmen.
