Verbal indications

b. 1

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

Indications in A (→GEFE,IE) & EE2

No indications in EE1

..

In EE1 the missing introductory indications are one of the many oversights in the initial fragment of the Sonata's finale. They were added in EE2.

The interpretation of the  hairpin in A, in spite of differing arms, seems quite simple – while writing the top arm, Chopin had to bypass the R.H. chord, hence we assume that it is the bottom arm that determines the intended length of the mark. In GE (→FE,EE) bar 12 opens a new line, which forced the division of the hairpin into two separate marks (it was one of the ways – in addition to the contemporary one – of reproducing hairpins in such situations). IE omitted the first one, probably due to the engraver's inattention.
In EE the cresc. indication in bar 12 was omitted, which could be a simplification of notation or an oversight.

In GE (→FE,EE,IE) the  indication was wrongly reproduced as , which happened a number of times in Chopin's pieces.

at beginning of bar in A & IE

..

Moving  to the 2nd crotchet in the bar was probably an inaccuracy by the engraver of GE (→FE,EE). According to us, the fact that the mark in IE is placed in accordance with A is due to another inaccuracy, this time by the engraver of IE.

di - mi - nu - en - do w A, contextual interpretation

dim. in b. 29 in GE (→FE,EE,IE)

..

In A Chopin divided the diminuendo indication into parts, which he then arranged over bars 28-30. The last entered part is ue, while the rest is missing. In the main text we complement this indication, keeping it proportionally spaced out so that the ending thereof falls on bar 31, which goes well with  in bar 32. The editions used a standard dim. abbreviation, placing it at the beginning of bar 29, which suggests a slightly later starting point of diminuendo than in A.
