There are 400 basic atonal syllables commonly used in Putonghua, and there are more than 1300 tone syllables (excluding light tone).
Syllables are arranged in a certain order, and the number of syllables is not very uniform. For example, the pentatonic scale used in oriental music is a typical example. The pentatonic scale composed of five different tones is divided into major and minor. The pentatonic scale and pentatonic scale are very close, with only simple ascending and descending.
