I've been trying to find out. Turns out the instrument is fictional; they just added in the sounds of other instruments. The "duduk" is the one with the melody. However, it's single-chambered and only produces one tone, not two. It'd be cool to invent such an instrument, though,
It's not called a pan flute. That instrument has many pipes put together. Peter Pan plays that "pan Pipe" not Mr. Tumnus. It might be some type of irish whistle, but all that seems to come up are those tin, or penny, whistles. If anybody knows the answer please spill those beans cause it's driving me crazy not knowing. >:(
The instrument looks and produces a sound of what is known about a greek aulos. If you want to learn to play this, sorry, but this instrument is mostly extinct, even though some have attempted to reproduce it. An aulos looks like two simple oboes, but is not connected like in the movie. The sound from the movie is somewhat would be expected from two instruments played by one person, where one is considered a changeable drone and the other half plays the melody (much like a bagpipe). The tune in the movie was produced by combining some form of drone with an armenian duduk for the melody.
I think its a version of a "Y double whistle", though these seem to not have fingering holes and are meant to be played by putting your hands over the openings and choosing how much air to let through . I suppose you could drill holes in one though.
Look up Native American flutes. They may not be the exact sound but they are the closest thin I've found. They have double neck and triple neck flutes so you can play a constant tone and a melody at the same time making it sound like two or even three people are playing.
Mr. Tumnus plays the flute to Lucy Pevensie in The Chronicles of Narnia. Lucy is one of the four main characters in The Chronicles of Narnia. The story of the book which is entitled The Chronicles of Narnia is set in the fictional world of Narnia. It was written by C.S. Lewis.
Mr. Tumnus is the name of a faun in the story which is entitled The Lion, the Witch and the Wardrobe. In addition to The Lion, the Witch and the Wardrobe, Mr. Tumnus has also appeared in the stories which are entitled The Horse and His Boy and The Last Battle.
He is described as a faun whose skin is reddish in colour. He has curly hair, a short, pointed beard, horns on his forehead and cloven hooves. His legs, which resemble those of a goat, are shiny and black in colour and he has a long tail which he carries over his arm.
