The abbreviated indication acceler. in A is repeated only in FE. GE and EE give the indication in its full form. In EE the indication accelerando was divided into syllables, which is a characteristic feature of that edition. In FE it is likely that the shift of acceler. over the last group of quavers may be an inaccuracy of the base text's recreation. category imprint: Differences between sources |

The sources differ in the range of diminuendo hairpins and placement of the indication dim. In A the hairpins begin between the 2nd and 3rd quaver, in EE under the 4th quaver, while in FE and GE under the 1st one. Moreover, in GE the range of hairpins was shortened, hence they include only bar 107. We adopt the notation of A and leave the typical for Chopin placement of dim. on an arm of the hairpins. category imprint: Differences between sources issues: Scope of dynamic hairpins |
