Missing performance indications in this bar (except pedal) are probably a result of an essential proofreading whose traces are clearly visible in FE. Initially, the L.H. part was the same as in the adjacent bars; at the same time, the f
minim was tied to the next bar. The presence of that tie suggests that the version was not a mistake but the original version. The fact that the proofreading did not include the majority of performance indications, present in analogous bar 159, may be explained by inadvertence of the engraver or Chopin's unwillingness to expand the range of the proofreading with elements that had been already indicated 4 bars earlier. Taking into account the fact that omission of the indications could have been of a random nature to a certain extent, we consider that it is advisable to add indications.
