Hello,
today I bought a wooden flute called Hohner Pocket Flute which looks like this: http://i54.tinypic.com/awsug6.jpg , but when I put the two parts of it together( fit perfectly) and blew( harder and weaker) , the flute didn’t emit any sound. 
It has no visible damages,has 8 holes and is empty inside.
Could anybody tell me what’s going on, please? 
Cheers 
Paulina
I would suggest that you take it to someone who knows how to form a flute embouchure. It probably works, although I’ve never seen this particular instrument.
As plunk says, you have to position your lips (and tongue) exactly right to produce a sound. This needs a lot of practice and training of your mouth muscles, and may take days or weeks or longer to get it right. The flute is not an “automatic” instrument. If you can’t manage this by experimentation on your own, find a flute teacher or player who can show you.
Interesting … This instrument looks like it uses recorder fingering. Maybe German F-nat fingering (look at the #4 and #5 holes). I wonder if there’s also a thumb hole on the back?
explains why Google comes up with sites that are in German
might be German…
Is that an offset 7th hole for the R4? Or is it just a knot or artifact of the photograph?
Best wishes.

I’d call up Pat Olwell and see if he would trade that Flute for one of his 
Germans can’t make Flutes, good beer though
Lat name German so I can poke fun at em!

Adam Schafer ( German Name)
I’ve heard they’re good nitpickers, too. And it’s Schäfer, not Schafer.
Maybe it’s a simple matter of blowing “over” the embouchure hole and not “into” it. You blow into recorders, whistles and Native American flutes. You blow over the hole on transverse flutes. You will never make a flute tone if you blow into the embouchure hole on a side-blown flute.
Is it plugged in?
There are a number of videos on you tube. might be worth having a look, but as others have said, it is not a straight forward process to be able to get a noise from a flute.
Good luck

That, my friend, made me laugh out loud…funniest post I’ve read in some time.

Paulina, what some of the ‘wise-guys’ haven’t pointed out is that you get a sound out of a transverse flute (the kind you’ve got) the same way you get a sound by blowing across a bottle.
A little more challenging, but the same principle.
The pointers to videos and You Tube for beginning flutists are an excellent start. A little time with any local flutist is good, or even a lesson with a teacher even better.
Stick with it, it’s a lovely instrument. . .

I thought of mentioning that, too. The problem is … It’s not the same principle.
On a flute you’re directing air at the sharp embouchure edge to produce a Karmann vortex stream which then acts as an air reed. Whereas a bottle acts as a closed chamber spring mass, and it’s the entire volume of air in the bottle that’s vibrating.
Consider that a bottle with a very smooth, rounded lip produces a sound just fine, because you direct the air down into the bottle. But a flute with a smooth, rounded embouchure edge wouldn’t produce any sound at all.
The physical action of the lips is a bit similar. But I figured some wise guy would come along and mention the difference.
Very good, then, Mr. Guru, Sir! Carry on. . .and I do mean carry on. . .

One other possibility. It shouldn’t be “empty inside”. The top piece should be blocked by a cork, or some kind of stopper. Is it missing?
Garry
Oh yes! That’s it! I haven’t tried turning it off and on again…
Yes, there is 7h hole. And there is also a hole for a thumb
cheers
