I love this song but I don't know what it's called or who it's by, and so I joined TC because I thought you guys might be able to help.
It's in
this video, from 1:23 to 1:57 and around 2:20 to 2:47.
I've heard this song so many times -- several of my old ballet teachers used it in class. It was always stuck in my head for days after hearing it, but I never had a chance to ask what it was called. Then, while watching Princess Tutu (a surprisingly delightful anime that incorporates a lot of ballet) today, I heard it again and decided that I really needed to find out who created it.
Anyway, if it helps, the music of that episode is mostly from Songs without Words by Felix Mendelssohn, so it might be part of an opus from the aforementioned.
And I really don't know much about classical music other than that I love to listen to it, so I apologize in advance for anything incorrect that I have written or may write.

I just want to find out what the song is called and who wrote it!
Thanks.
EDIT: Also, I'm terribly sorry if this isn't the right place to post this thread. I was a bit uncertain as to where this would fit best.
