In the notation of A it is not entirely clear where Chopin wanted to begin stretto or how far the dashes marking its range are supposed to reach. Therefore, it comes as no surprise that the remaining sources reproduce those details differently, which we consider inaccuracies, with the exception of the version of GE, in which the dashes are led as far as to the beginning of b. 19, which is clearly contrary to the notation of FC. In the main text we assume that stretto is to be combined rather with g2 than a
1 and that the dashes reach f1 in b. 18. The major divergence from the Chopinesque notation is to be seen in CGS, in which stretto is written in the middle of the 1st half of b. 16 and the dashes only just in the 2nd half of b. 17, as a result of which it is actually unclear how they are to be considered jointly (in that copy, just like in FE, the entire indication is placed between the staves). It was probably caused by lack of space between the staves.
