We give the pairs of hairpins, appearing under similar figures in the L.H. in these bars and their repetitions in the entire Etude, in a unified version for each of the sources, in spite of the fact that the marks differ in their range. Same as in the case of slurs, the regularity of the texture and numerous repetitions of similar figures contribute to the decision not to consider these minor divergences in transcriptions.
