b. 40

composition: Op. 10 No 7, Etude in C major

Long accents in A

FE (→EE)

Short accents in GE

Possible short accents in A

..

In FE (→GE,EE) the accents were assigned to the right hand and put over the upper stave. The notation of A is ambiguous in this respect, therefore, in the main text we place the signs between the staves. In GE short accents were used, in accordance with this edition's most frequent manner of reproducing all "accent-like" signs of different length featured in FE. Also in this aspect the notation of A is not entirely unanimous, hence we permit an alternative interpretation of the accents as short.

Our suggestion

..

According to us, the comparison with the accents from the previous bar suggests that both the placement and the kind of accent written in A (FEGE,EE) may be interpreted in two ways, which we include in variant suggestions.

Slurs in A

No slurs in FE (→GE,EE)

..

The notation of the next line, overlapping with the slurs under the pairs of chords in the L.H. in A, was certainly a reason for their omission in FE (→GE,EE).

Accent &  in A

No signs in FE (→GE,EE)

..

According to us, omission of the long accent at the beginning of the bar and the  hairpins at the end in FE (→GE,EE) is a result of distraction (haste) of the engraver of FE.
