Since the day of birth, Leyou has been acting as a bridge for the Bouyei men to get married. It shares the honor and disgrace with the Bouyei people, conveying the joys and sorrows of the Bouyei people; Today, it has become a sacred musical instrument widely loved and recognized by the Buyi people. Among the music that expresses national emotions, Leyou is the most expressive, and occupies a major position in national musical instruments, being one of the main instruments.
The reason why Leyou is unique is that it uses insect cocoons to make a whistle, and the sound it emits has a tone between an oboe and a suona, which is brighter than the tone of the oboe and softer than the tone of the suona. Therefore, its timbre is soft, beautiful, bright and lingering, making it sound like a nostalgic and endless aftertaste. On and off in the band, suitable for lead and solo. In the Bouyei people's "small beat music" and "eight-tone" music, they often appear with unique timbres, showing that young men and women of the Bouyei nationality love freedom and yearn for happiness.
The reason why Leyou can represent a national musical instrument is because it has its own uniqueness. As people say: when you hear the sound of cucurbit, you will think of the water-splashing festival of the Dai people; when you hear the sound of the reeds, you will think of the wind scene of the Miao people. So, what about when you hear Leyou's music? You will naturally think of the "wave whistle" (love) of the Bouyei people.
In the villages of the Buyi nationality, the boys began to learn to play Leyou from an early age. In the evening, whether in the mountains, fields or villages, the melodious and lingering Leyou tunes come from everywhere, making people indulge in a sea of music and love. The girls know what's on their minds when the lads play the Leyou tune. Especially on the night when the moon and stars are sparse, the young men use Leyou to call their lover or lover by the river, on the bridge, in the field, or by the bamboo forest. The girls will know that the other person is missing and calling for them. At this time, the girls will try their best to meet and talk with each other. Because the villages inhabited by the Buyi people are surrounded by mountains and rivers, the scenery is charming. Just as the sunset is shining, there are everywhere: the sound of leaves, the love of the bamboo tube, the thoughts of Leyou, and the love of chaff. It can be said that "a piece of bran wraps a heart, and a piece of wood leaves a piece of love. Brother Chuleyou misses his sister, and the sister uses a bamboo tube to convey love. Blindness across the mountain and deep affection across the river."
