Pipa, erhu and flute are called the "four great pieces" of national musical instruments.

"Valley dance, lonely girl crying, Du Gongbu suddenly heartbroken, Yu Chenglong temples cream". China's flute has strong national characteristics, with moving pronunciation and beautiful sounds. The ancients called it "the sound of washing", so the flute was originally called "flute" and later evolved into today's flute. Flute is an important melody instrument in Chinese national bands, which is mainly used for solo and ensemble. The beautiful and moving Butterfly Love in Fairy Sword OL is mainly played by bamboo flute.

Dulcimer-combining rigidity with softness

Dulcimer and stringed instruments. Also known as dulcimer, piano player, brass piano, fan piano, bat piano and butterfly piano. Dulcimer is an indispensable instrument in Chinese national bands. Whether it is used for solo, accompaniment or ensemble, it can give full play to the timbre characteristics of dulcimer. Dulcimer has a loud and elastic voice, but its personality is not very strong, so it is easy to blend with other musical instruments. When playing slowly, the timbre is like a ding-dong mountain spring, and when playing fast, the timbre is like running water. The excellent overall score of "Xian Jian OL" can not be separated from the embellishment of dulcimer.

Pipa-magnificent

Pipa is a plucked instrument, made of wood, with a semi-pear-shaped speaker and four strings. The neck and panel are equipped with "phase" and "quality" to determine phonemes. When playing, it is an important national musical instrument that can solo, accompany and ensemble. Pipa performance is magnificent and has a strong national style, which conforms to the China martial arts style of Xianjian OL.

Erhu-touching the heart

Erhu is a traditional stringed instrument in China, also known as Huqin, Erxianqin, Omzi and Tribal Tiger. The melodious timbre of erhu can often touch the listener's heart, and the most touching music in "Fairy Sword OL" also has its accompaniment.
