The beginning of the 4th movement of Beethoven's "The Hunt"

[rachorascho]

Hello,
I am currently learning this sonata and in my urtext edition the beginning of the 4th movement is signed with piano dynamic, but it is in brackets like if I do not have to respect it. There is a reference to Detailed Notes, which unfortunately are not the part of my edition. In other non-urtext editions that I found on imslp is always except one edition signed piano without brackets. Does anyone have some explanation for those concrete brackets in wiener urtext?
I know it is not really that important, I am just curious.
Thanks in advance

My guess would be that the autograph lacks a p dynamic here, but that it can be inferred that he probably intends you to play piano based on like the dynamics at the repeat of the exposition and recapitulation. I don't have my own urtext here but I can check later. But the above would be my guess.

In my Henle edition (not the new Murray Perahia) the piano is marked with " *) "  and there is a note that says the English First Edition marked a forte. I think piano makes the most sense. Great sonata choice by the way

I think expectation is that you do both--the left accompaniment should of course be very quiet and light, while the melody should be very clearly defined, perhaps like the entry of a solo instrument into an orchestral texture; this can be much more forte than the left-hand.

Thank you all!
