Because the sound range of traditional cucurbit is relatively narrow, people add keys on the basis of traditional cucurbit according to the needs of performance. After adding keys, the same supervisor has five more notes than before, which expands the application range of traditional cucurbit.

Hulusi can be divided into northern cucurbits and southern cucurbits according to the place of origin. The northern cucurbits have an open, broad tone and a loud voice; Yunnan cucurbits have a mellow, sweet and clear tone. Generally, the Dai people are good at playing this kind of cucurbit.

Do not cross your legs to avoid affecting the flow of breath. ;Stand naturally with your feet slightly apart or parallel to your shoulders, keep your body's center of gravity between your legs as much as possible, lift your chest naturally, don't put your arms close to your body, just shrug your shoulders naturally, and relax your body naturally.

The sound principle of cucurbit silk:

Hulusi is a reed-pipe-coupled vibration musical instrument. There are three types of high, medium and low bass, and commonly used tones such as D/E/F/G/A/B/. The differences in local customs and regional environments among various ethnic groups make the cucurbit flute musical instrument also different in structure.

The range of the cucurbit flute is not like the familiar bamboo flute, which can reach more than three 8 degrees, usually within 9 degrees and no more than 11 degrees, which is a national scale. Its beauty is soft and delicate, round and simple, charming and expressive, and is deeply loved by the people. Whether it is folk music or professional stage, you can hear its beautiful and beautiful sound.

The structure of cucurbit silk:

Hulusi, the Dai language is called "bilangtao", "bi" is a general name for wind instruments in the Dai language, "lang" means straight blowing, "bi"

The local Chinese is also known as the gourd flute. The shape and structure of cucurbit silk is unique. It is made of a complete natural gourd, three bamboo tubes and three metal reeds. The whole gourd is used as an air box. The bamboo tube part is set with a copper or silver reed. The bamboo tube in the middle is the thickest and has seven sound holes. It is called the main tube. (referring to the traditional cucurbit silk), it can only emit harmonics that resonate with the supervisor. Usually the desktop attached tube makes a "3" sound, and the right attached tube does not sound (or a low 6 tone).

This musical instrument uses a gourd as a sound box and a gourd mouth as a mouthpiece. It is common to use three bamboo pipes of different lengths each equipped with a spring, which are inserted into the bottom of the gourd side by side. The whole body is about 30 cm long. There are also single-pipe, double-pipe or four-pipe. No matter how many bamboo pipes there are, the middle one is usually in charge, and the rest are adjutants. There are 7 sound holes on the main pipe, the first six and the rear one. The traditional cucurbit silk auxiliary pipe does not have holes above it, but only opens at the bottom of the pipe body. It is blocked with a plug. The plug and the pipe body are wired to connect, and the little finger is used when needed. turn it on. The improved cucurbit silk does not use the traditional plug, but opens a sound hole on the pipe like the main pipe.

This is more convenient for the repeated use of the auxiliary pipe sound when playing, and the control is free and more flexible. When playing, the fingers control the sound holes of the main supervisor to play notes of different pitches. If the main and auxiliary pipes are turned on at the same time, several pipes will sound in unison when playing. The melody only comes from the main pipe, and the auxiliary pipes are only set off by a harmonious and continuous single tone, usually a One tube makes a sound, and - tube makes e sound, which produces a harmony effect, giving people a subtle and hazy beauty.
