b. 142

..

In addition to the cautionary  to a2 written by Chopin, GE (→FE,EE,IE) put another one, to a, which we include also in the main text.

b. 142

composition: (Op. 4), Sonata in C minor, Mvt IV

Crotchet f1 in A

No note in GE (→FE,EE,IE)

..

The omission of the f1 crotchet at the end of the bar could be related to its position. In A this note is on the top stave (the other L.H.-part notes are on the bottom one), between the last notes in the R.H. part, which could have confused the engraver.

The position of the  mark in bar 142 in the middle of the 2nd demisemiquaver sextuplet is almost certainly inaccurate – see the note in bar 141. The same applies to the  mark in bar 143. In the main text we provide a contextual interpretation of both marks, which coincide with the structural division of the figuration – marked by, e.g. harmonic changes – into whole-bar sections, starting from the 2nd quaver of the bar.

b. 143-147

composition: Op. 43, Tarantella

Crescendo in FE (→IE), EE

No crescendo in A and GE.

..

In A and GE there are no crescendo and decrescendo dynamic markings in bars 143-147.

b. 143

composition: Op. 43, Tarantella

..

In A before the last quaver in LH there is no diminishing to g. This is an obvious inaccuracy in Chopin's notation.
