Best Service Gu Zheng
Oriental Virtual Instrument
Gu Zheng, recorded by local Chinese music producers
Gu Zheng is one of the most beautiful, traditional Chinese instruments with a history of more than 2000 years. The modern Gu Zheng is a Chinese plucked zither equipped with 21 strings and movable bridges. Basic playing styles include plucking at the right portion and pressing at the left portion to produce pitch ornamentations as well as tremolo. Yellow River Sound's Gu Zheng is produced by Zhang Jian (China Conservatory of Music) & Ma Jing (ADSH) in cooperation with Best Service. For the first time, a Chinese instrument was sampled with great care by local Chinese music producers, who have a natural understanding of their culture and a sole passion to express the true quality of Chinese instruments.
Using the Best Service ENGINE sample player technology, this virtual instrument offers more detailed articulations than ever. Its freshness and elegance reflects the preserved spirit in Chinese culture. While many virtual instruments are involved in the loudness war, YRS Gu Zheng's low-velocity samples allow you to experience the sound of silence, nevertheless, its wide dynamic range also provides punchy impact.
