Please reccommend some Mozart pieces

[jugular]

I've been self teaching myself for the past few years, so I've mainly been playing pieces by composers that I enjoy- this limits my playing style greatly! I've NEVER played a piece by Mozart, although I'm familiar with a few themes from his piano concertos, not too many though. Here's a list of pieces I have under my belt at the moment...

-Beethoven Sonata No.8, Op. 13 (Pathetique) Mvmts 1-3
-Rachmaninoff Prelude Op.23 No.5
-Chopin Polonaise Op. 53 (Heroique)
-Beethoven Sonata No.21, Op.53 Mvmt 1

What would you reccommend I start with for my first Mozart piece?

Any of the Sonatas. Listen to a few and pick one you like. Or just read through the lot and pick one that way.

Agree with the above -

It seems as though you perhaps like "famous" ones though. To me, the most recognisable themes from the sonatas can be found in the 1st and 3rd movements of K331, and the first movement of K545.

K545 is probably the easiest of all the sonatas..

...

If you haven't already I'd recommend playing through a bunch of clementi/kuhlau sonatinas first though. Considerably easier than the works you list above, but don't underestimate the benefits of exposing yourself to a greater amount of music, as well just works that are likely to give you some work technically speaking. (not that there isn't technique to work on in easier material).

Edit:
Not a sonata, but K 265 is arguably fairly well known too.

Many of the sonatas may be quite challenging for one who isn't accustomed with the sense of touch, tone, and phrasing that Mozart's piano music requires. Though there are a few that would work well as starting points (and should be quite manageable for you if you have the technique to play the repertoire you listed well), I would personally recommend a shorter piece first as an introduction to Mozart's style. A particularly lovely work is the Fantasia in D minor K.397, which almost seems to foreshadow the Romantic era with its drama, daring harmony, and virtuosity. A very unusual work for Mozart, but it will definitely be an easier transition to his works for someone who is more accustomed to playing Romantic era works. I also recommend the rondos, particularly the gorgeous (and underplayed) A minor, K.511.

Contrary to JCarey, I won't recommend the D minor Fantasy nor the A minor rondo. Both are highly mature work and requires a lot of finesse and thorough understanding of Mozart's idioms. I have not heard many good rendition of the D minor Fantasy played by students even though it is often played. I would second what j-menz recommends: run through a couple of the sonatas; some of the sonatas have easier movements: such as K. 279, K. 280 (2nd), K. 282 (2nd), K. 283 (which is my favorite for starting my students on Mozart sonatas, since I dislike K. 545), etc.
Have fun.
