It seems that Chopin hesitated how to mark the climax of the crescendo in this bar, which started in bar 27. In the original version, known from CLI, in which in the L.H. there is a semibreve, the climax is naturally shaped at the beginning of the bar, where the E
major chord and the highest note of the melodic line appear. In the final version, the octave leap in the bass somehow complicates the situation – an additional accent appears on the syncopated minim. In Ap both elements were taken into consideration, there is a 
sign at the beginning of the bar and 
under the syncopation. However, in the version prepared for printing Chopin left – in accordance with the visible in the entire Etude tendency to reduce the number of indications – only and the accent, placing both next to the minim. According to us, the sign may in Chopin's intention embrace with its range both the second beat with the syncopation and the beginning of the bar.
