b. 57

composition: Op. 10 No 7, Etude in C major

In GE2 (→GE3GE4) the characteristic for Chopin rhythmic notation of the L.H. was replaced with a notation that is compliant with the rules, yet more complicated in terms of graphic: .

It is unclear how the change in placing the  indication occurred – it may be either an error of the engraver or Chopin's correction. In this kind of endings Chopin generally embraces the entire chordal ending with , e.g., in the Etudes in C minor, No. 4 and G major, No. 5, Waltzes in E major, Op. 18 and A major, Op. 34 No. 1, Variations in B major, Op. 12 or Bolero in A minor, Op. 19. Due to this fact, in the main text we adopt the unequivocal version of A. From the practical point of view, the difference in placing  is signficant only when we adopt the dynamic concept in bars 56-58 written in FED.

In GE and EE mark was added at the end of the piece. Leaving the endings of the works without this mark is characteristic of Chopin and in some situations it can have a practical meaning.
