The five tones are gong, shang, jue, zhi and yu, corresponding roughly to do, re, mi, sol and la in Western notation. Much traditional Chinese music is built on five-tone scales, and the term wuyin ("five tones") was sometimes used to mean music in general. This is a simplification rather than a rule covering all Chinese music: five-tone scales also occur in many other musical traditions, Chinese music uses other pitches as well, and a scale alone does not describe the style of any particular period, region or tradition.
