Issues : Deletions in A

b. 27

composition: Op. 25 No 4, Etude in A minor

​Third a-c1 in A (→FE)

Fifth f-c1 in FC (→GE) & EE

..

Both source versions of the last quaver in the L.H. are a result of corrections, certainly (A) or most probably (FC) authentic. Out of these two practically equal versions, to the main text we choose the a-c1 third written in A (→FE). According to our evaluation, the corrections in the L.H. visible in A also in the next two bars prove a thought-out decision of the composer, including all sound aspects of the accompaniment in this fragment.
