I agree with most of the posts including the last one. It is very easy to draw a line under this and move on. Beethoven was never ambiguous with his directions for pedalling, fingerings, phrasing or indeed anything else with regard to performance, whether piano music, chamber music, orchestral, choral etc. He was one of the most meticulous and fastidious composers and performers in history. There is no doubt at all that in his piano music, certainly from Op.26 onwards he is very, very clear and precise as to where the pedal is required and where it is not. (Even allowing for changes and developments with piano design over time. That is opening another can of worms for debate!)
Some editors do confuse matters, but always look at Beethoven's own original directions. A good edition will always make it clear as to those directions which are those of the composer, and those which are suggestions by the editor.
Anyway, I personally prefer Urtext which is as close as you can get to a composer's original intentions. With regard to the first movement of the sonata Op. 27 no.2, it is very, very clear indeed. At the beginning, after Adagio Sostenuto, Beethoven writes "Si deve suonare tutto questo pezzo delicatissimamente e senza sordino", which essentially means that "The whole piece must be played very softly and sustained throughout - ie using the right sustain pedal" These are Beethoven's own instructions and should not be ignored. If they are ignored then the effect intended just will not happen! Accounts of Beethoven playing this sonata himself confirm this, as well as his use of the left Una Corda (soft) pedal.
Therefore, how anyone can say that playing the piece without sustain pedal makes it sound "less spooky" beggars belief and just reflects a complete lack of understanding of Beethoven's unequivocal intentions, as well as a shallow and naive view of piano techniques generally. Beethoven is right because he was the composer and was very clear about the overall effect he desired in performance. Even in the finale to this sonata, Beethoven is absolutely clear where the sustain pedal must be used and where it should not. These are the composer's pedal marks, not the editor's, certainly in Urtext.
Another composer who is well known for having been very, very clear with pedal and other performance directions was Chopin. Also, when you go to a piano concert, don't just watch the pianist's fingers, watch their feet too; this is just as important. You can't pick this up from audio recordings, though video recordings may help providing the camera has been set up in a long shot where you can see the pedal work too.
Just as a final point in relation to a previous post, it has already been said, but Barenboim you are so wrong! You said:
"senza sordino means using NO pedal in that movements!
In italian senza means no, hope this will help lot of pianist because this is one of the most reapeated errors." Your tone is very pompous, but you are completely wrong!
Senza does mean NO, but actually, you clearly do not understand what sordino means. It does not mean pedal, but 'mute'. I do not wish to sound pompous in return, however this needs to be asked? Why are you posting stuff in this section when you clearly don't know what on earth you are talking about? I also find it slightly amusing, but mainly extremely irritating that you have taken the name of one of the greatest Beethoven interpreters of all time. Listen to the real Daniel Barenboim playing Beethoven, then you might just learn something about piano technique!
