The traditional music of CHINA can tell a story or paint a picture in sound, express ideas and even influence people in how to live their lives for the good of all.  The idea of composing music for its own sake was foreign to Chinese culture and its classical music was not for wide audiences but a more private art form.  Plucked and bowed LUTES, used in traditional folk music, are very high pitched and again based on the pentatonic (5 note) scale. Melodies are performed in unison (all playing and singing the same notes) with elaborately modified versions of the melody played at the same time. The Chinese invented numerous musical instruments, such as the Zheng, Qin, Sheng, Xiao and ERHU that have later spread throughout East Asia and Southeast Asia, particularly to Japan , Korea and Vietnam .
