In this harmonic and textural context, the missing  must be considered Chopin's oversight – in the section that ends here the pedalling allows to put the chord specifying the harmonic contents on the previously played bass notes, whereas starting from the next bar, the use of pedal is no longer necessary to build the sound of subsequent chords (although it is by all means possible). The mark was already added by GE (→FE,EE,IE).

b. 58

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

Tied minims in sources

Semibreve suggested by the editors

..

To the main text we introduce a simpler version of notation, as in analogous bar 219. The tied minims in the sources must be remaining elements of an earlier version, e.g. minims without ties. See also bar 66, 94.
