The missing tie of a
1 is almost certainly a mistake of Chopin, who did not introduce the changes performed in the R.H. to the L.H. It seems that a1(2) at the beginning of bar 158 was to be originally repeated – the crotchet in the part of the R.H. was even provided with a staccato dot, deleted then probably when a tie was added. This scenario is confirmed also by the dots over the crotchets at the end of bar 157 – see the note dedicated to them. A tie was added in EE and GE2.
