In a 1.8 flute the top open of the bore is 2 cm decreasing to 1,45 and enlarging again to 1,8cm... If I change the length from 1.8 to any other, this measures will change in the same proportion?

Henrique,

Here is a link to 12 graphs of bore profiles from 1.3 to 2.4.

http://www.shaku8.com/makeshaku8/data/naikei.html

These measurements represent a composite of many conventional shakuhachi whose bore measurements have been averaged for each length of flute. If you look at the different sizes, you'll notice that there isn't a clear ratio found when moving from size to size.

Keep in mind that there is no standard bore profile for any size shakuhachi. There is actually a wide window of bore profile possibilities for each size. That window is much wider than what is represented in these bore profiles.

Hope this helps.

Ken

Hi Ken

I will take a careful look into this graphs and compare them with the flutes that I have in hands waiting for some bore work...

With the windows of mind also open to ideas and attentive ears to discern the little sound changes in every attempt when working the bore... I'll try to do my best... without haste...

Thank you for the tips...

Peace

Just in case you can't find this important piece of the puzzle....

it's the location/size of the finger holes for every bore profile...

Hi...

Thank you Jacques... of course this information will help a lot too.

I have another question... Are this bores measures taken from flutes of the same maker?

Oh, yes I miss this detail in my translation...

One time ago I read a history about a king who wants to make a bed with a lot of diamonds to put on guests room... He ask the joiners to do a bed exactly in average of citizen of the kingdom...He also said that the people who was not in the bed sizes can have his legs cut down or then to have the body stretched to be exactly of the size of the bed... So the joiners take the measures of all citizens and then make the calculations of the average size of a man...After the bed gets ready and a lot of dead people after, the king gets into the conclusion that a person of the medium size doesn't exist...

Thank you for calling my attention Edosan.

Peace

Only very tall or very short people

One quote famous version of this has to do with measuring the emperor's nose in China. Here's a link for that one:

http://www.imaginatorium.org/stuff/nose.htm

The basic idea is that your results won't magically become more accurate just because you took lots of bad data and calculated the average. If the people honestly have no idea about his nose then the results won't be meaningful.

This is, however, slightly different from taking averages of known lengths. In that case you have data which can be proven to be good and you take an average out of that. Although it doesn't guarantee that you get a good number to use for your flutes this way you at least have a good number to start with. At least you know that values that differ dramatically from the average may not work that well.

Yep, throw out the stray data points and only use the ones that fit your hypothesis. That's called "scientific method".

Yep again. I'm on hour 8 of 12. 12 hour work days are nice though, it gives you a lot of days off.

Indeed they do. So much, in fact, that I currently work two days a week and that's it. I got this job primarily so I could focus on shakuhachi practice during the weeks while still being able to pay for ramen and lessons. I figured that nothing's going to happen unless I take this stuff seriously. Just telling everyone how serious I am isn't going to cut it in the long run unless I actually start doing something about it.
