b. 11

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

..

In EE1 the quaver beam starts from the second note and ends on the fifth one. The mistake was rectified in EE2.

b. 24

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

Tie to g in A & IE

Slur in GE (→FE)

No sign in EE

..

GE (→FE) put the tie to g under the bottom stave, which turned it into a vague curved line. EE omitted it, and it was only IE that guessed Chopin's intention.

b. 28

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

Crotchet d2 in A

Quaver d2 in GE (→FE,EE,IE)

..

The version of the editions, in which the last d2 note is a quaver attached to the L.H. part, resulted from a misunderstanding of the misleading A notation – the d2 crotchet stem (bottom R.H. voice) almost reaches the e1 quaver written on the top stave.

b. 28

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

a2 tied in A (→GEEE,IE) & FE2

a2 repeated in FE1

..

The lack of a tie to a2 is undoubtedly a mistake of the engraver of FE1, corrected in FE2.

b. 38

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

g repeated in sources

g tied, our suggestion

..

In the main text we suggest adding a tie to g due to the notation in analogous bar 24 and 202. It is likely that the tie could have been overlooked in A, as the bar opens a new page.
