What is the name of this song?

I'm trying to figure out the name of the song that starts 3:15 into the clip. I have a lot of the notes figured out on my violin, but I'm stuck about 3:48 into it. If you can help me with either locating the song or figuring out the notes, I will be forever grateful!

Sounds like Bach. But that's the best I can do right now. Let you know if I can find it.

Hmm I Really Don't Know But I Like It. I Tried Translating the Title.. But Of course, That Didn't Help Very Much. Anyway The Title Came up As "I reported your First"..

I don't know but I have used Google translate to post a comment (in Spanish) to the person who posted the clip.
So watch for a reply.
