Some transverse flutes and a shakuhachi I made from copper tubing I got from a junkyard. Tuned to different, mostly modal tunings (let's give a big YAI for dorian here, folks!)
They are working OK, considering that I have never seen a pro flute... Mostly I would need some advice on the embouchure(?) hole.
The shaku doesn't really work, plays only one octave. I guess the wall should be thicker, now it's only 1,5mm... It's also quite hard to keep the right angle when blowing. Then again, maybe I'm just a lousy player.
Filed & brushed the surface for extra beauty, and then heat treated for oxidation colours.
Oh, and they're toxic too, probably. Any advice on this is appreciated.
In the future, will stick to stainless probably... Or maybe aluminium? Does aluminium tubing exist?
And it's NOT cheap, around here copper is 6 euro/kg at the junkyard...
