Abstract

The utility model relates to a "seven-hole flute", which is based on the modification of the existing "six-hole flute". The length of the pipe body is the actual length of the vibration of the air column in the pipe, and an additional side hole is opened between the end of the pipe and the first sound hole of the lower handle, and the little finger that has been idle for a long time in the six-hole bamboo flute is used to press and close it. This "seven-hole flute" aims to fully inherit and retain the advantages of the traditional "six-hole flute" in terms of structure and fingering, and replaces the original pitch hole and auxiliary sound hole by adding a side hole to the lower handle. The range of the traditional bamboo flute can be extended downward by a minor third and upward by a major second, and the total expanded range reaches a pure fourth, which has achieved an important breakthrough in the structure and performance range of the Chinese bamboo flute for thousands of years.

Description

seven hole flute

technical field

The utility model relates to a wind instrument, in particular to a novel bamboo flute with seven finger holes—the seven-hole flute.

Background technique

The traditional "six-hole flute" ("six-hole" and "seven-hole" mentioned in this manual refer to holes) is widely popular today because of its unique charm, and has become one of the most simple and classic Chinese folk musical instruments. device. This "six-hole" system of the traditional Chinese bamboo flute has actually been handed down for thousands of years, and has remained almost unchanged (only in modern times, the uniform hole is changed from the uniform hole to the non-uniform hole). Since the 1950s, many people have carried out various reform experiments on this wind instrument, such as adding holes, adding keys, increasing, shortening, etc., but none of them can replace the traditional six-hole system.

So far, there are various styles of adding holes to the traditional six-hole flute, such as "ten-hole flute", "nine-hole flute", "eight-hole flute" and "seven-hole flute". There are two main shapes of the "seven-hole flute" seen in it: one is to add an additional sound hole on the upper back of the sixth sound hole of the traditional six-hole upper handle (press with the thumb of the upper handle) to facilitate the sound of the tube. The cover of portamento and palace tune (referring to accompanying drawing 1, among the figure 36 is the sixth sound hole, and 51 is the additional sound hole); The 2nd is to add a sound hole between the first sound hole and the second sound hole of the traditional six-hole lower bar Additional sound hole, to facilitate the performance of semitone and transfer, is more common in big bass flute (referring to accompanying drawing 2, among the figure 31 is the first sound hole, and 32 is the second sound hole, and 52 is the additional sound hole). All the above-mentioned reforms (including ten-hole flute, nine-hole flute, etc.) have one thing in common, that is, they do not change the structural characteristics of the six-hole flute’s flute tail with the fundamental sound hole and the auxiliary sound hole (the tube sound and the first sound hole are always the same). maintain the interval relationship of a major second), and cannot widen the actual performance range of the traditional six-hole flute. Breakthrough is of little significance; in addition, due to the addition of additional sound holes, it has a greater impact on traditional fingering, and the gain outweighs the loss, so it cannot replace or shake the traditional six-hole flute that is widely spread.

Utility model content

The technical problem to be solved by the utility model is to provide a seven-hole flute with a wider sound range on the basis of retaining the existing playing technique of the six-hole bamboo flute. The technical problem to be solved can be implemented through the following technical solutions.

A seven-hole flute is based on the modification of the existing six-hole flute. Its specific shape is as follows: firstly, all four pitch holes and auxiliary sound holes of the flute tail of the traditional six-hole flute are abolished, so that the length of the pipe body is equal to the air column in the pipe. According to the actual length of the vibration, an additional side hole is opened between the end of the pipe and the first sound hole of the lower handle, and the little finger that has been idle for a long time in the six-hole bamboo flute is used to press and close. The position of the additional side hole opened is about two-thirds of the distance from the end of the tube to the first sound hole.

The seven-hole flute described in the utility model is based on completely inheriting and retaining the "six-hole" structure and playing fingering of the traditional bamboo flute, and replaces the original pitch hole and auxiliary sound hole by adding a side hole to the lower handle. method, so that the range of the traditional bamboo flute can be extended downward by a minor third (two or three more tones can be added), and upward by a major second (for the bangdi, this expansion will be more obvious), and the total extension of the range reaches a pure The fourth degree has achieved an important breakthrough in the structure, shape and playing range of the Chinese bamboo flute for thousands of years.

Detailed ways

As shown in Figure 3, it is the structural form of the "seven-hole flute" described in the utility model. Taking the tune flute of D as an example, the system of its flute tail is: additional side holes 4 and original six sound holes (referring to the holes) ) The pitch of the first sound hole 31 in 3 is about 4.3 centimeters (the interval relationship is a major second degree), and the distance between the bottom of the tube and the additional side hole 4 is about 8.2 centimeters (the interval relationship is a minor third degree). Hole 4 is roughly located at the end of the tube at two-thirds of the distance from the first sound hole 31. It is pronounced as the "sign" (sol) sound of the basic tone (replacing the original tube sound), and the tube sound of the new tube body expands downward to "angle" ( mi) sound, and the rest of the upper structure is the same as the traditional six-hole flute. The setting angle or height of the additional side hole 4 is suitable for the little finger to be able to hold it naturally.

The "seven-hole flute" described in the utility model is modified by adding a side hole (little finger hole) and a flute tail structure (abolishing four fundamental sound holes and auxiliary sound holes), and the side of the pipe body is placed under the six holes of the traditional bamboo flute. An additional sound hole (pink hole) is opened, and the length of the pipe body is the actual length of the vibration of the air column in the pipe, that is, the length of the pipe determines the height of the fundamental tone (no fundamental sound hole and auxiliary sound hole), so that the traditional six-hole bamboo flute can On the basis of retaining the original playing technique, its range can be extended downward by a minor third interval, upward by a major second interval, and a total of a pure fourth, making the range of the traditional bamboo flute reach nearly three octaves. Take the Bangdi whose third hole is in the key of "F" as an example: its lowest pitch is a of "Small One Character Group", while the highest pitch reaches the g of "Small Character Four Group", which is wider than the range of the traditional six-hole bamboo flute. A full widening of a perfect fourth.

In actual performance, if the little finger does not press and close the additional side hole of the "seven-hole flute", the sound produced by the hole is just like the "tube tone" of the traditional six-hole flute, and all the playing fingerings and feelings are exactly the same as the traditional six-hole flute; Press and close the additional side hole with the little finger, and you can get a deep bass extending down a minor third. You can also half-close the additional side hole to obtain the required major and minor second intervals depending on the needs of the music and multi-house cover. At the same time, due to the change in the structure of the flute tail, the "Shang" sound in the high-pitched range that the original six-hole bangdi could not play at all can also be easily obtained.

In addition, the distance between the pipe tail of the "seven-hole flute" and the additional side hole can also be shortened (formed a major second relationship) or lengthened (formed a major third relationship) according to the needs of the tube sound interval in actual production.
