This new adaptation of a one-octave scale exercise by Carl Czerny uses an inverted A section in place of the original B section. This gives both hands the same scale exercise as well as equal practice of the I, IV, and V7 chords. "Czerny Study" can also be found in Practical Lessons for Piano - Book 1 by Jared Metzger Abel.
