In GC, the beginnings of slurs in bars 159, 167, 175 and 183 are clearly placed above the 1st beat of the bar. Such notation may have been intended by Chopin in order to underline the four-bar resounding of the chords ending each one of the choral phrases. However, another possibility is that the notation is simply inaccurate here - there are many places in GC with imprecisely written slurs (and this is how the matter was generally interpreted in GE). As the main text we give the slurring of EE and FE, free of errors or doubts, where the slurs begin on the 2nd beat together with quaver figurations. The issue occurs in other similar fragments that begin in bars 203, 291, 307, 453, 497.
