I hope I'm writing to the correct board. I found this forum by browsing on the internet and it seemed to have a nice and active community.
I don't have much experience with flutes other than the plastic recorder I had at school. However, I'm interested in music and musical instruments, and few days ago I decided to try build myself a transversal bamboo flute.
I've been reading a bit about the topic and I came to the conclusion that I would build something similar to the chinese "dizi".

I found these sites quite useful for calculating the right proportions:

My flute is in the key of B, these are the details:

Units of measurement: cm
Inside Diameter 1.2 Wall Thickness 0.15

diameter: 0.70
distance from end: 32.285000000000004

1st hole
frequency: 932.33 A#
size: 0.55
distance: 17.578

2nd hole
frequency: 830.61 G#
size: 0.55
distance: 15.378

3rd hole
frequency: 739.99 F# 5
size: 0.55
distance: 12.924

4th hole
frequency: 659.26 E 5
size: 0.45
distance: 9.988

5th hole
frequency: 622.25 D# 5
size: 0.55
distance: 8.591

6th hole
frequency: 554.37 C# 5
size: 0.55
distance: 5.203

end of flute
frequency: 493.88 B 4
distance: 0

I managed to build it (i had some problems smoothening out the inner nodes though), and I can play notes on it, even though I don't have experience with this kind of embrochure.

My problem is, I can play quite well the higher notes (A#5, G#5, F#5), but when I try to play the lower notes I have problems to get the sound right. It feels almost easier to play on the higher octaves.

I will try to make my blowing technique more precise in the next days, but I wonder, did build my flute in the wrong way? Would it help to make the inside part more smooth, of modify the embrochure?

Thanks in advance!

...possibly because it is?
Which is probably because the ID of 1.2 cm is a bit on the small size for a B Flute - smaller id => weaker, or even nonexistent low notes, too big ID => hard or impossible to play high notes
Of course it could be something else!
