Which tone is less in Japanese tone

Japanese music often uses do\mi\fa\ra\xi.

Japanese folk music uses a pentatonic scale. The most commonly used tuning of Japanese folk songs is called "Japanese folk song tuning" (original: folk scale), and its tuning scale is the same as the La-Re tuning in China, with the feather (6) and the merchant (2) as the nucleus tones, and the melodic progression and the basic tones of the Japanese folk songs are based on the four-degree tritone scale (such as 6 1 2 or 3 5 6, etc.). ). In addition, the tuning of Japanese folk songs is also based on the "Ritsu-tuning style" (the tone rows are equivalent to the five-tone levitation style of China).

The ancient Chinese tuning system is also divided into twelve semitones, and the names of each tuning system are Huang Zhong, Da Lu, Tai Tu, Jie Zhong, Gushu, Zhong Lu, Lei Bin, Lin Zhong, Yi Ze, Nan Lu, Wu Shuo, and Ying Zhong, which are produced according to the method of five degrees. It was created according to the five degrees of phasing method. Later in the Ming Dynasty, the twelve equalization laws were created. These twelve names are also the names of the tones used by the ancients, with a fixed pitch. The pitch of the first law, Huang Zhong, is equivalent to f 1 of the current international common meter.
