I'm currently a full-time music education major and need a lot of help on a project. The project is over Mozart's Fantasia in c minor, KV 475. We are to answer 20 questions along with writing all of the modulations and Roman numerals. I'm really struggling to find the correct modulations, and this causes problems with writing the Roman numerals. It's really hard to tell if the accidentals are embellishments or if they are actually a part of the modulation. If anyone can help, that would be great!
I am not able to post images, but the score can be found on IMSLP.
