The fundamental reason is that there are different understandings of the same temperament due to culture. Ancient China and ancient Greece proposed the same temperament almost at the same time, but they had different names. In ancient China, it was called the three-point profit and loss method, and in ancient Greece, it was called the five-point law. The law of reciprocity.

The essence of the two temperaments is the same, and the degree of the note is determined based on the ratio of 2:3. However, ancient China's use of temperament was based on two calculations of profit and loss to arrive at the five tones. The ancient Greek law of fifths is based on five independent operations, resulting in seven tones. This is the fundamental difference between the five tones and the seven tones. Later, during the Western Renaissance, the twelve equal temperaments perfectly matched the seven-tones, thus consolidating the seven-tones and promoting them all over the world as a scientifically based temperament.

China’s understanding of Eastern culture’s music is based on the artistic conception of mountains and flowing water, and the music law used is: the three-point profit and loss method. The three-point profit and loss method is three times and the result is based on the five tones of Gongshangjiao and Zhengyu as the basic tones. These five tones correspond to Do (Gong), Re (Shang), Mi (Jiao), So (Zheng), and La in Western music. (feather). The degree of the pentatonic scale is more in line with the harmonious temperament, and at the same time it has a more stable sustained artistic conception effect.

In addition, it is also because our cultural and traditional musical instruments are generally elegant arts and exclusive to the nobility. However, most of the musical instruments that ordinary people come into contact with are transmitted by word of mouth and from master to apprentice, which cannot form iterative progress and systematic education. In this way, the music audience is smaller and the musical atmosphere is lower. Because there are too few preservation and music education frameworks, there was no substantial progress or improvement in musical instruments when we first proposed the twelve equal temperaments. The Western Equal Temperament has directly completed the promotion and application of all musical instruments, and dominates today's music theory.

The seven tones in Western culture were first proposed by the law of five tones in the ancient Greek period. The law of five tones is essentially the same as the ancient Chinese three-point profit and loss method, but the degree of application is different. The law of five tones is The number of iterations is greater than the ancient Chinese three-point profit and loss method. Later, until the Renaissance era, the West entered the era of twelve equal temperament. The twelve equal temperament is essentially a fundamental improvement of the law of profit and loss in three points or the law of mutual generation of five notes. It solves the problem that the law of profit and loss in three parts cannot be eliminated in mathematics. At the same time, based on the improvement of the first wavelength of hearing by the human ear, the natural rhythm based on human hearing is derived. The biggest reason leading to the promotion of seven-tone music is the popularity of the twelve-tone equal temperament in the West.

The fundamental reason for the spread of seven-tone music is that the twelve-tone equal temperament has become the core of Western music. Twelve equal temperament incorporates the pure temperament to form a diatonic scale dominated by seven tones, and also incorporates the gain and loss method of thirds, and adds five additional tones to form twelve equally divided octaves. Finally, the promotion of twelve equal temperament was completed on modern pianos, and finally all classical and modern musical instruments completed the universal promotion and application of twelve equal temperament. At this time, we were in a semi-closed communication and had not yet completed our musical sovereignty.

Based on the five tones of ancient China and the seven tones of modern Western countries, this leads to musical differences between the two cultures. To put it simply, our music types nowadays tend to be concentrated in the broad category of Chinese style, while Western music is completed based on the seven-note theory: jazz, blues, rock, folk, reggae, funk, Ramp; B, soul music , gospel, new age, country electronic and other types of music. Essentially, from the perspective of popular music, the twelve equal temperament around 1600 based on the natural scale is more suitable for the development of human music than the law of thirds or the law of fifths.

In fact, whether it is the Eastern five-tone or the Western seven-tone, they are essentially born out of the twelve rhythms of music. The Twelve Rhythms of music are the laws of music in nature and are also the smallest unit of music that our human ears can feel. This point, whether from the East or the West, has the same theoretical feeling.
