Does anyone know where I can get one of these whistles or what they are called. It has one mouthpiece but two bodys and it gives it a bagpipey (lol) sound almost. The little creature on the beginning of the Dark Crystal played one, and the faun on the old wonderworks “the lion the witch and the wardrobe” by C.S. Lewis played one too methinks. I could never find one though. 
Is this close enough? http://www.tinwhistles.us/whisethnic.htm
Scroll down to the Bi-whistles, which are not what they sound like… 
I believe they’re called Gelfings. I have no clue why I remember that. 
Because it was the greatest film ever™.
Anyway, Jen the Gelfling played something shaped like a “Y”,
which looks like a forked piece of wood that was reamed out, so each
arm of the Y would be fed by one fipple, or maybe by individual
internal reeds like an Indian pungi.
Here’s a painting depicting the instrument in question (I’ll try to do a
screengrab from the DVD tonight if anyone cares):
I think making a whistle that truly mimicked this would be diffucult
in reality, since each arm would actually need its own fipple in order
to make independant notes. I think Daniel Bingamon’s biwhistle is the
closest musically, if not visually.
Also, the person playing a fairy at the Carolina Renaissance Festival
this year appears to have cobbled together a biwhistle by gluing two
whistles together at the head, with some bracing halfway down, and
covering half the holes on each whistle. It is somewhat visible here:
BEAUTIFUL!!!
And the whistle looks nice too.

The sound of Jen’s flute was actually made with a double recorder-like instrument. It’s called a double-flageolet, an English Regency instrument acquired for the film because of its characteristic capability of simultaneously sounding two independent pitches.
Erik The Flute Maker makes those if you’re interested in getting one.
Indeed! Perhaps I should frequent renaissance fairs a little more often.
No doubt!
Yeah, she’s not sore on the eyes.
Interesting, thanks. I wanted to ask her if she made it herself, but alas, her
character is speachless. She mostly goes around charming little children
with pixie dust and music, and stealing the hearts of their fathers…
Another possibility that you may be loolking for is the Launeddas or Argul.

The fairy is cute - but also looks to be 12-14 years old.

I disagree, but then, I’ve seen her in real life. She’s at least 20.
Those are some sexy whistles! Probably like learning a whole new instrument though. Do two bodies whistles have to have two reeds?..I though one side maintained one pitch and the other had a normal six whole thing going on.
would it be possible for any well known whistlesmith to make one out of say aluminium or brass, one fipple with two bodies (just like a split normal whistle) so that it would be easier to play?
guess it takes a lot of hand co-ordination though…
any takers?
