Issues : Alterations in GC

b. 18

composition: Op. 35, Sonata in B♭ minor, Mvt I

..

In FE1 two mistakes were committed in this bar, corrected in the subsequent impressions: on the 4th quaver of the bar there is a1-e2 instead of g1-e2 and f1-g2 instead of f1-fon the 6th quaver. The remaining sources include the correct text (in GC one can see a correction of the top note on the 4th quaver of the bar from f2 to e2).

a1 in chord in GC (→GE1)

f1 in FE (→EE) & GE2

..

The version of GC (→GE1) is certainly erroneous – the double stroke of the same note (a1) by the L.H., unjustified by the voice leading, does not make any sense, as far as the piano technique is concerned. It is worth observing that the copyist initially wrote a chord within the correct, one octave, span, yet with a double Terzverschreibung error – a-c1-e1-a1. He then corrected it, yet only partially.
