b. 173-174

composition: Op. 21, Concerto in F minor, Mvt III

Slur in A, contextual interpretation

Slur in GE (→FE)

Triplet slur in EE

2 slurs suggested by the editors

..

We interpret the slur of A, started at the end of a page in bar 173 and unfinished on the next page, in accordance with the notation of bars 169-179 and the slurs in the R.H. in bars 169-170 and 171-172. The absence of the slur over (under) the triplet in bar 174 must be Chopin's oversight. The slur of GE (→FE) is probably a result of a Chopin proofreading of GE1, whereas the slur of EE – of a revision. In the main text we give two slurs modelled after the slurs in the R.H.

b. 173

composition: Op. 16, Rondo in E♭ major

..

In FE (→EE1), there is no  restoring c3. The unquestionable oversight, probably repeated after [A], was corrected in GE and EE2 (→EE3).

No indication in AI & Af (→FEEE)

cresc. - - in GE

..

The clarification that it is also this culminant phrase that unfolds further until the critical chord in b. 177 seems to be an improvement introduced into [AG] (→GE). It is the first out of an entire group of additional markings in GE – cf. b. 177, 177-180, 180-188, 185, 189-191.

Long accent in AI

Long accent in AF, contextual interpretation

Short accent in FE (→EE)

Short accent in GE

..

In AF the accent in this bar is shorter than in the next ones. A comparison with AI shows that it is almost certainly an inaccuracy, which, however, could have influenced the interpretation of this and next marks in FE (→EE). GE also features a short accent, which does not have to mean that the notation of [AG] was also ambiguous. The issue of placement of this mark, between the staves, is slightly more difficult, and we discuss it in more detail in the next bars. In this bar we place the mark in the main text in the middle, in accordance with AI.
