Description

Reed-separated keys and sound barrels and combination instruments

technical field

The invention relates to the technical field of national musical instruments, in particular to a reed-separated key press, a sound horn and a combined musical instrument.

Background technique

Mang tube, a single-reed gas-sounding musical instrument, is mainly popular in the Miao, Shui, Dong, Yao and other ethnic minorities in Guizhou, Guangxi and Hunan. Large-scale mango teams usually consist of 15 or 21 mango tubes, which are divided into 4 groups of large, medium, small and minimum, each group ranging from 3 to 5, which together with different reeds form a reed band. The mango can strengthen the main tone with its unique rich and round continuous sound, thus enriching the sound of the whole band. The tube body of the awn tube is usually made of bamboo, which is composed of two parts: the tube body (resonator tube) and the blowing tube. The blowpipe is usually made of a thin bamboo tube, the bamboo joint is transparent, the mouth of the upper end is used as the mouthpiece, the lower end is left closed, and a small rectangular hole is opened at the bottom, inlaid with a piece of copper, and there is no pressing. sound hole, so only a single tone can be produced. The resonance tube is made of a thick bamboo tube. The upper end of the tube is cut into a 45-degree slope shape, and the middle bamboo joint is opened. There are two shapes at the bottom of the tube, which are open tube or closed tube: the common bottom end is left. Closed, that is, the tube is closed; the other is to dig a triangular or semi-circular small hole on the side of the tube body above the bamboo joint at the bottom, put the reed pipe at the bottom of the resonator, and blow the air flow when blowing the mouth on the upper end of the reed pipe. Make the reed vibrate and make sound, and the resonator can expand the volume; the blowpipe is tied to the mouth of the resonator with a cloth strip or rope. When playing, the end of the blowpipe inlaid with the reed often shakes, causing the reed to fall off easily. According to the different specifications of the resonator, the pitch of the mango can be divided into treble, alto, tenor, bass and double bass, etc., and form several octaves in turn in a coherent band, but the pitch is raised and joined in the ensemble. The reeds are the same.

The traditional mango tube is hand-made by folk artists, and the material is bamboo. The reed inlaid at the end of the blowpipe is prone to pitch problems when exposed to water, and the reed may even be damaged after long-term use. It is inconvenient, and the bamboo is corroded after being soaked in water, and it is easy to burst due to the change of temperature difference, which will increase the trouble and cost for the maintenance of the awn tube.
