At the IMDB board there is trivia concerning the movie Harry Potter Deathly Hallows part 2, which is the last movie of the whol series. It is written in the trivia that this is the only movie in the series that an Armenian Duduk is used for the opening WB credits and beginning. Only one I can think it is would be "Lily's Theme - 01" which is very ominous. If you go to www.youtube.com and do a search for "Lily's Theme" you will most likely find the music clip and listen to it.

Was this really a Duduk that was used?
