louispodesta, you seem to be replying to a different question. The question in this thread has nothing to do with pedalling and there is no F natural in the measure preceding the one shown here.
In any case, a quick look at another edition confirmed my suspicion: the natural sign is just badly placed. The top two notes of the chord are E natural and D flat. The same chord appears at the end of the following measure.
If you play the chord with an E flat and a D natural, it not only makes no harmonic sense: it also, as the OP remarked, sounds hideous.
1) Unfortunately, as of late, I take an OP at their word and assume that they have already researched other editions. So, I used a method common to all pianists of the late 19th and early to mid 20th centuries, and I used pedaling to bring in the F natural early for it to carry over into the next measure.
2) You, like many others who have viewed my original thesis, still view my work as heresy.
3) Yes to some ears, the first score sounds odd, however, composers and editor publishers have made mistakes forever. That is why "Your Piano Teacher Taught You Wrong" because you always take the score/scores for granted, regardless.
Daily, I correct mistakes in original editions. As a case in point, I cite a composer by the name of Poulenc.
And, what is my usual solution? I take the heretical path, and I obtain several recordings of the piece. Then, I listen as to how a concert pianist's ear and their advisor/producer interpreted a particular work.
In the future, I suggest that the OP and others take the listening approach, which will lead them to a logical conclusion regarding the accuracy of any score. As a case in point, I obtained a copy of Gabriel Tacchino's recording of the aforesaid Poluenc Piano Concerto.
Why? Because, his piano teacher (his only student) was Poulenc!!!
