Hello to everybody! Greetings from Spain!

I have built seven PVC shakuhachis (1.8, tuned in D)

I can get all notes of lower (otsu) octave with nice and rich sounds, =
but I have put all my efforts to get any sound of high (kan) octave with =
no results but the first two notes (ro and tsu). I've tried hard to =
'overblow' to get these sounds. Actually I play silver flute with no =
troubles....These are my theories:

1. The PVC pipe cannot reach such high frecuencies because of its rigid =
structure...
2. My technique is wrong.

What's wrong with PVC and Kan octave??

Please, enlighten me with your wisdom...

Thanks in advance.
