Rhythm

b. 15-16

composition: Op. 39, Scherzo in C♯ minor

..

In EE f is not tied, which is an obvious mistake.

b. 31

composition: Op. 39, Scherzo in C♯ minor

Rhythm in EE, GC (→GE1) & FE

..

The version of GE2 is completely arbitrary: the rhythmic variant from that bar does not occur in any of the other sources. There are no reasons to suspect a mistake, either.

b. 34-35

composition: Op. 39, Scherzo in C♯ minor

No tie in EE, GC & FE

Tie in GE

..

In GE the minim g sharp in bar 35 is sustained with a tie from the previous bar. This is probably a revision resulting from misunderstanding of Chopin's notation, which is confirmed by the omission of an accent above that note. A similar situation occurs when the fragment is repeated in bars 376-377.

b. 37

composition: Op. 39, Scherzo in C♯ minor

..

Missing in GC are three augmenting dots for all the three minims in that bar. That obvious omission was corrected in GE.

b. 47

composition: Op. 39, Scherzo in C♯ minor

Rhythm in EE & GC (→GE1)

FE & GE2

..

Both versions of the rhythm in that bar are probably authentic. Identical rhythmic differences between those sources also occur in analogous bars 129 and 389. In the main text we give the version of FE, probably the latest one.
In GE2 the rhythm of that bar in the version of FE was introduced in all the analogous places. Such standardization has no justification in the sources.
