Description

[Detailed description of the invention] The purpose of this invention is to obtain a shakuhachi that exhibits excellent temperament, volume, sharpness, pitch, and timbre when played, and that can be easily produced. shall be.

The present invention has a longitudinal hole 1 extending from the outer surface of the tubular body to its interior.
A shakuhachi comprising a wavy wall 7 in which finger holes 2 are opened through the shaft and are slanted from the outside to the inside, and a wavy wall 7 is provided with a wavy ridge in the internal vertical hole 1. Although the tubular body may be one piece like a conventional shakuhachi, in the present invention, the tubular body is divided into two equal parts, or two parts that can be considered the same, and the male pipe 3, A female tube 3a is provided, and an insertion tube 4 is provided at the inner end side of the male tube 3 (inner end when configuring a tubular body).
is provided protrudingly, and is fitted and connected to the inner end side (same as above) of the female tube 3a to form a single piece, and the fitting is configured to be freely insertable and removable. That is, it can be assembled and folded freely. The insertion tube 4 has a length suitable for connecting the male tube 3 and the female tube 3a. 5 and 5a are decorative rings which also serve as reinforcement, and 5 is fitted and fixed to the connecting portion of the male tube 3, and 5a is fitted to the connecting portion of the female tube 3a. Therefore, several finger holes 2 according to the present invention are formed in the tubular body at appropriate intervals or at appropriate locations. Of course, bamboo can be used as the material for the tubular body of the present invention, but wood suitable for making shakuhachi, such as
So-called hardwoods such as maple, karin, rosewood, ebony, and redwood are suitable for manufacturing, and if the outer surface of hardwood is polished, it will give off a glossy luster. Other types of wood, bamboo plywood, plywood mixed with these materials, plywood mixed with various materials appropriately, or
Any synthetic resin material (such as FRP) is suitable for manufacturing. Finger hole 2 in this invention
It is easy to manufacture because it can be mechanically tilted to expand its depth in a diverging shape. 6 is a concave groove provided around the outer end of the male pipe 3 (the outer end relative to the inner end) when the tubular body is made of hard wood such as maple; It is best to slightly expand it into a trumpet shape, as in the case of . Internal vertical hole 1 of tubular body
The wall forms a corrugated wall 7 provided with corrugated ridges. 8
indicates the mouthpiece, and 9 indicates the knot. In addition, the above tubular body,
The male tube 3, female tube 3a, and insertion tube 4 are appropriately painted.

The operation of the present invention will be explained based on the above embodiment. When the insertion tube 4 of the male tube 3 is fitted into the female tube 3a and the positions of the blowing port 8 and the finger hole 2 are arranged, the tubular body are assembled to form a regular shakuhachi,
The insertion tube 4 is pulled out from the female tube 3a, and both are placed together and stored in a portable bag or wrapped in a wrapping cloth. In addition, if the tubular body is a single piece rather than an assembled or foldable type, it follows the general usage of shakuhachi. In the present invention, the finger is opened and closed by touching the finger hole 2,
This is the same as the usual method of emitting a blowing sound.

In the present invention, the finger hole 2 is inclined from the outside to the inside in a divergent shape and is bored with respect to the internal longitudinal hole 1.
Since the shakuhachi is opposed to the wavy wall 7, it has the advantage of having a richer range of temperament, volume, sharpness of sound, width of sound, timbre, etc., and can be played better than the conventional shakuhachi.
