Essential Finger Exercises - Ernst von Dohnanyi - Piano Editio Musica Budapest Softcover

In the following exercises, I have endeavoured to collect material in consensed form, yet as complete as possible, which should help piano students to acquire a reliable technique. They are even all-sufficient for finished pianists to keep in training, and to retain the already acquired technique.' Ernst von Dohníçnyi (Budapest, June 1929.)
