Here is the finished files
I included an .mus, .xml, .wav, and .midi. I preserved all of your original notes, except for one measure where I added three notes that were badly needed. I also added dynamic, artistic, and performance markings. I used traditional italian marks, so if you have trouble understanding them you can either ask me, or find an online musical dictionary. I have changed the piece into the correct key(s). I have also corrected all notational problems. I hope you don't mind that I added my name on the sheet as the editor. Please tell me what you think. If there are any problems, or if there is something that you want changed I will be happy to change it. Again, I'm sorry it took so long for me to get this finished.
