The "Pratten" bamboo flute

I made this “Pratten” flute out of bamboo, the lower, thick-walled part of the plant. It is not an easy task as the

pieces selected need to correspond to the desired “Pratten” proportions after reaming and turning, the softer inside

part of the bamboo rod is taken out and a hard, bodily pipe is the end result. I have been trying to find an

alternative way to use this material for a long time because of its excellent acoustic characteristics. The first

piece, treated with tung oil is ready and under testing. I have been playing on it reagularly for a month and the

instrument seems stable. It doesn’t crack, keeps its shape. These were my concerns about the new prototype, but

so far my experienes are absolutely positive.


Here is a sound clip https://www.youtube.com/watch?v=lwOCo2CIJ64

That’s a handsome instrument. If you make this work, you’ll have done the wooden flute world a huge favour.

That’s very cool. I was expecting just another typical stick with holes burnt into it (I’d already dismissed the “Pratten” part), but this is new ground to me. If the ferrules can successfully control cracking, then bravo. Sounds pretty decent, too.

That is very cool, nicely done.

Nice job! That looks and sounds great!

In the photos it looks like the upper part of the left hand body section is made of the same material as the tuning slide, but the rest of that section seems to be a different color/finish, and like the right hand body section, foot and head. Is the left hand body section made from two different pieces of bamboo bonded together?

Thank you :slight_smile: Yes I combinate an other piece on the left hand
section..It was needed to fit well with the midle part.Its
putit on like a ring.I turned of from the piece and
put on a thicker part and and after that just turned them together.
I had to choose the sulution because you cant find
that thick piece of bamboo whitch is gives out the size
for reaming and fitting well with the uper piece..

We’re very intereted. Can you explain what makes it a Pratten, as opposed to some other model?

Yes..Thanks for your quastion..I build this flute following the parameters of Boosey Pratten’s.Its not exactly the same but there are just very small differences. Its a conical bodied flute made of bamboo with a Pratten flute parameters. The midle body section is from two piece witch is different and offcourse on this flute there are no keys. In the “original” Pratten flute plans the midle part is made from one piece of wood.I had to make the midle boudy section from twoo pieces because I coudnt select that long piece of bamboo whitch gives out the sizes for reaming and turning.I also made for it a fully lined headjoint.With the fully lined head I find more loud and more complex the sound.In the sound clip I used the half lined head joint witch is a bit softer than the fully lined one.

Very interesting idea, and impressive work! I hope you’ll keep us updated on how this idea progresses.

I have not seen bamboo reamed and turned like this before. This is very interesting. Do you use the same turning tools and reamers that would be used for hard woods, or does bamboo require a different approach? Of course, I understand if you don’t want to share all your secrets! :smiley:

I have no secrets:) Yes Im using exactly the same tools (drills,reamers etc.)for bamboo that Im using for hard woods like blackwood..Just I have to work with it more carefully than with hardwoods.

Congratulations and keep up your pioneering work. The product looks attractive and sounds pretty good too. In an age where the future of sustainable exotic hardwoods is uncertain, the idea of a flute made from such an abundant alternative natural material seems like good forward planning. I suppose, as you have already mentioned yourself, the only immediate problems are finding and matching suitable diameter cane, and the extra care and time involved during construction. It also will be a very lightweight instrument in the hand ( never a bad thing ) and also having a cane flute that can be dismantled and transported in a case is also novel and quite practical. If you can reliably source enough suitable cane for your purpose, you may well be on a winner with this type of flute. Have you found any need to treat the cut ends of the cane to prevent moisture absorption ? Good Luck and every success with your future cane flute endeavours.

Beautiful work and a great idea!

Thanks for all of your comments:)Realy! Yes its very important to impregnate this material very deep and close the pores..Im playing on it regulary every day sins a month and it seems that is absolutely stayable.Actualy I selected material for a fiew more flutes.I prepared them for work with but first I leave them
to have rest for while before reaming. Just the same like with woods.Im planing to make some other keys as well with this metod like F and Eb.

Congrats, your work is amazing.
Have you thought about adding keys to your wonderful bamboo flutes?

Thank you Smoro Yes Im planig to make a keyed flute as well..The wall of this bamboo is thick enough to add "metal"blocks for keys.. I have to figure it out first:)

I am looking forward to see that keyed flute!
