This exercise combines an Alberti bass pattern and held bass notes in the left hand. The opening right hand line features repeated quarter notes, in order to facilitate mastery of the left hand pattern. The right hand line in the second section is more interesting, requiring students to achieve a greater level of facility with the left hand pattern. Rather than repeating the first section verbatim at the end, Czerny uses a varied repetition of the opening pattern, which challenges the student to combine additional rhythms in the right hand with a familiar chord structure.
