3.2 When I adjust it without changing the length of the "尺八"
When three "ロロハ" (E) matches, and other sounds do not match
(1)A principle and instructions of the tuning
①Pitch, the resonance is with the balance of the area of the position, the hole of the
overall hollow volume, hole including a pipe and the hole I do
I tune it while regulating all holes little by little generally, and seeing balance
Please avoid tuning by 1 hole
②When you bury a hole, please fix the shape of the hole as a hole is transformed by
tuning and the painting at the time of the production
③The materials to bury, please use bamboo and I process it to a shape to bury
④Mark it naturally, and is superglue; attention deep is quick and adheres
⑤I can finish coming over, and there is business and finishes knives at the surface of
the hole
(2)Raise the pitch of the hole (the chart below left)
①It is diagonal in a hole in the manner of composing "歌口" direction I remove it
surgically in this (the chart below left)
②The shape of the hole greatly collapses and I cut it in a form near perpendicularly
as possible and should lack when there is not it (in the center chart below)
③When a hole grows too much big, I bond a bamboo to the opposite direction
(the chart below right)
④When pitch greatly comes off, I bury a hole and empty a hole again
(4)Lower the pitch of each hole
I perform whether you keep away the position of the hole from "歌口" to lower pitch by a
method making a hole small
(method 1)
①Bury a bamboo in near a "歌口" to lower the area of the hole and cut it after the
adhesion
②Sharpen it to incline judging from the side
③Lower the area of the hole in the pipe little by little and match pitch
④Finish the area of the surface hole without changing it not to show it as processed
(method 2)
①Bury a bamboo in "歌口" near one
②Form the bamboo which I buried in a circle to become the hole
③Sharpen the other side of the hole in a circle little by little while confirming pitch
④When pitch greatly comes off, I bury a hole and empty a hole again
(3)When pitch of soprano "ヒ" is low(when 五 of ヒ is low, I apply it)
When pitch is low even if I sharpen 4 hole
①For example, the pitch of "ヒ" of １尺６寸 is (D), but must be equal with 五 of "ヒ" (D)
It is an important element deciding a sound of "ヒ" at the position of 5 holes that decides
this pitch
②When the position of 5 hole is at the remote position from "歌口", influence pitch of the
soprano; low
In addition, I influence "三 of ハ,四 of ハ" and lower
③I raise a resonance frequency to correct this because it travels the position of 5 holes
in near a "歌口" do
I can raise pitch of the soprano. This work is similar to (The upper figure right).
④Until pitch of "五 of ヒ" agrees with "ハ" E; close do
As a result, the soprano becomes higher, too, and the sound becomes sweet, too
