Hulusi, as a traditional wind instrument of ethnic minorities in southwest China, has been deeply loved by music lovers for its beautiful, deep feeling and poetic tone. So, what exactly gives fenugreek such intoxicating sound?

First of all, the design and construction of fenugreek silk has a decisive impact on its timbre. The main body of fenugreek is composed of natural gourd and bamboo pipe. Gourd as a resonating cavity, the warm and soft characteristics of its material itself make the sound of fenugreek with a natural, simple and warm feeling. The part of the bamboo pipe, according to the length and diameter of the different, can produce different pitch and timbre, coupled with the resonance effect of the bamboo itself, so that the tone of the fenugreek is more clear and melodious.

Secondly, the pronunciation principle of fenugreek also determines its unique timbre characteristics. Fenugreek adopts reed sound. When blowing, reed vibration produces basic sound, and the subsequent breath is reflected and superimposed inside the bamboo tube, forming a special overtone structure, making the timble sound rich in layers and charm. At the same time, fenugreek playing skills, such as glissando, pronunciation, Boeing, etc., can further enrich and improve its timbre expression.

Thirdly, the range of fenugreek is relatively narrow, which makes its timbre more concentrated and pure, easy to create a deep and distant music atmosphere, especially suitable for playing lyrical and romantic songs, giving people a deep touch.

To sum up, the reason why fenugreek has such a beautiful tone, in addition to its unique design and structure, it is also closely related to the pronunciation principle, playing skills and vocal range characteristics. It is the combined effect of these factors that makes the tone of hulusi unique among many Musical Instruments, and has become an indispensable treasure in Chinese musical culture.
