Wide-range Ba-wu flute

Abstract

The invention discloses a wide-range Ba-wu flute comprising a bass main pipe, a high pitch main pipe and a combined casing pipe. The bass main pipe and the high pitch main pipe are arranged in parallel, and are respectively matched and sleeved on the combined casing pipe; six sounding holes are arranged on the bass main pipe in parallel, and are divided into three upper holes and three lower holes according to fingering; and four expanded range holes are arranged on the high pitch main pipe, and are correspondingly arranged in parallel to the three lower holes. According to the wide-range Ba-wu flute provided by the invention, the additional arrangement and structural design of a chord tone hole are omitted, and the expanded range holes are smartly moved downwards and are arranged corresponding to the three lower holes, so that the expanded range holes can be expanded to be four sounds. On the premise of ensuring the tone quality, the range is greatly expanded really, and the play range of the Ba-wu flute is greatly widened. The wide-range Ba-wu flute can be smoothly played from the bass main pipe to the high pitch main pipe, so that natural hand shape, flexible fingers and convenience in play can be realized. By utilizing the wide-range Ba-wu flute, all the sound-to-sound playing way and the rapid sounding way can be realized in play. The wide-range Ba-wu flute can be used for playing chord tones and the like.

Description

technical field [0001] The invention relates to a wind instrument, in particular to a wide-range bau. Background technique [0002] Bawu is an ancient famous musical instrument in our country. Its timbre is elegant and loved by the majority of musicians. However, Bawu has a narrow range and is only suitable for playing a few relative range music. In order to expand the range of Bawu, several kinds of music have been proposed Improvement plan, one of the better improvement methods is to use two Bawu bundles to form a double-tube Bawu, which can achieve the effect of expanding the sound range by using different fingering techniques without changing the law. At present, a common structure of double-tube Bau is as follows: figure 1 As shown, it includes a first main pipe 1', a second main pipe 2' and a composite casing 3', and the composite casing 3' is provided with first blowing nozzles which communicate with the first main pipe 1' and the second main pipe 2' respectively. 3...

Problems solved by technology

[0003] Compared with the traditional Bau, the existing double-pipe Bau has added chord effect sound elements in its design, but the actual sound expansion effect is limited. It can only expand two tones, and cannot play wide-tone scales, that is, from the perspective of sound range At present, the double-tube Bau has not been able to achieve a real wide-range effect, and still cannot meet the performance needs

In addition, the lower three holes on the first supervisor 1' and the sound range hole 21' of the second supervisor 2', which are both controlled by the lower hand position, are far apart, and the control of changing the pipe needs to be interrupted, so it is impossible to realize continuous operation. Tone and fast spit sound performance, add that the second mouthpiece 32 ' is positioned at the lower position of the first mouthpiece 31 ', and the operation of changing the mouthpiece and controlling the opening of the range hole 21 ' is reversed, so the finger cannot be brought into play in the performance. Flexibility, unnatural hand shape, inconvenient to play

Furthermore, there is a relatively large gap between the first mouthpiece 31' and the second mouthpiece 32' on the composite casing 3' at present, and the cavity change control must be interrupted, so that rapid cavity change cannot be performed, and the performance will also be affected to a certain extent.
