Everyone (or at least every musician) has that one piece of music that they absolutely dream of playing. For my sister, it's this one, the lovely and lively Movement III from Beethoven's Violin Concerto in D Major!
I haven't heard the other two movements of this particular Concerto (I hear that they're maddeningly difficult though, more so than this one if that's believable), but this 10 minute piece feels pretty complete in and of itself. It goes through several different moods and stages, and always returns to the bright, joyful melody you first hear the violin playing at the very beginning. There are very impressive runs and cadenzas, and I think that this piece very successfully showcases pretty much everything that is awesome about the violin.
Libby here, Xochitl let me write a bit because I play violin :) One of the things I really like about this concerto is that unlike a lot of violin concertos the ENTIRE orchestra gets to play so it sounds really big and impressive, concertos that don't use the entire orchestra aren't bad but this one would sound really dorky without it XD I think this is my favorite concerto, its really happy and it uses the entire violin, even though that can make it really hard to play, it sounds great :D
