How does Bright Line differ from traditional erhu music? Considering the background of the times, why did this piece of music come into being?

"Bright Walk" is an erhu piece with strong national characteristics, which has some significant differences from traditional erhu music and also reflects the specific background of the era.

First of all, in terms of compositional background, "Bright Walk" is a piece born during the war period, composed by Liu Tianhua, a famous erhu player and composer in China. During this period, China was experiencing a deep national crisis, and the people were eagerly looking forward to light and hope. Liu Tianhua, as a musician, used his music to express his longing for a stable life, his desire for light, and his confidence in the future.

Then, from the point of view of musical elements, "Brightness Walking" incorporates new elements into the traditional erhu music. It adopts bright and fast patterns, such as fast and sharp, which makes the music have a more vivid rhythm and strong momentum. Meanwhile, in terms of melody, it adopts a lot of bright and warm tones to express the yearning and pursuit of light.

Looking at the playing technique, "Brightness" is also innovative in erhu playing technique. It utilizes frequent glissandos and vibrato, as well as playing techniques with strong contrasts in intensity, making the music more expressive and infectious.

Thus, "Brightness Walking" is not only different from traditional erhu music in terms of musical elements and playing techniques, but it was also created in a specific period of time, reflecting a nation's yearning for a stable life and expectation of brightness in a chaotic world. It represents the hope and belief of people in that era, and is a musical work with profound historical significance and high artistic value.
