there are truly countless valid interpretative possibilities for this piece, although I certainly prefer a certain type of interpretation. here's a few (be sure to click on the listen to story button):
https://www.npr.org/templates/story/story.php?storyId=18577817there is continued argument about the use of the pedals. I personally think that if beethoven had meant una corda (left pedal), he would have written it, as he does in several of the other sonatas. the trouble is the use of the term "sordina" which literally means "mute" or "damper," but is interpreted in different ways by various people. does this mean without the use of pedal? does this mean with the pedal depressed? which pedal does he mean? I take it to mean that one should use the right pedal throughout, but I change the pedal with the shifting harmonies. I think this is the most widely accepted interpretation. for more confusion about pedals, look at the instructions at the beginning of the 3rd movement. depress both pedals? turns out, beethoven's piano at the time had a damper pedal for the lower register, and one for the top. so anyway, how are we to interpret this on our modern pianos? further-furthermore, some of the earlier sonatas have omitted bass notes where beethoven ran out of room on the piano of his day. my piano can go that low--should I "fill in" the blanks or play strictly as written?
by the way, this piece is not written in common time, it's written in cut time. sorry I forgot to mention that in my previous post.
one more thing: google "schiff guardian uk," and you will find a series of lectures on each of the sonatas by Andras Schiff. I don't agree with all of his conclusions, especially about the moonlight, but you will definitely learn a lot about beethoven's music if you listen to all of them.
