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.
