In the movie "Titanic", the tune on Rose's music box

I am trying to find the name of the little tune playing on Rose's jewelry box when her fiancee gives her 'the heart of the ocean' (the big blue diamond. It is near the beginning of the movie, about 15 minutes in.) Thank you in advance for your help---Annie

I don't know for sure if this is right, but a search on the web led me to this:

"Tales From The Vienna Woods" by Johann StraussII

(listen at the 0:50 mark)

This piece of classical music occurs exactly 45min.38sec. into the movie, when the fiancee of Rose gives her the big, blue diamond (La Cur de la Mer), or "the heart of the ocean"it is being played on Rose's music box; just long enoughfor someone very brilliant in ID to identify this piece. And no, I don't think it from "Tales of the Vienna Woods".Thanks so much if you can crack this case. ---Annie
