Does music have to be tonal?

Musical tonality continuum is one of the latest harmony techniques and tonality analysis theories, and its compatibility range is the whole sound spectrum.

After the 20th century, with the development of science and technology and the evolution of culture, music language showed a diversified trend. Nowadays, in the 2 1 century, it is even more "unexpected and impossible". Tonality analysis and composition technique theory began to face crisis. At this time, a new theory is needed to support the effectiveness of future music analysis.

Inspired by Hua Cuikang, I rearranged this theory. From the perspective of continuum, there are five (eight) categories of musical (or sound) sounds from tonality to atonality:

Category [musical structure consisting of only one tone]: For example, the first movement of Mirica RiCelata by Righetti, Monotonous Cannon by Carter, and Tai Chi by Zhao Xiaosheng.

Class A [familiar rule, the core of the structure's pitch organization is a pure fifth interval with a span of no more than 5]: for example, the kind of pop rock with "only a few chords".

A+~ B type [familiar law, the core of the structure's pitch organization is a pure fifth interval with a span of more than 5]: such as Beethoven's later works and Brahms' works. Part of Beethoven's passages can reach the level of Class C, and Bach's negative seventh chord may also reach Class C instantly, but only temporarily.

Class B [familiar with the law, the core of the pitch organization of the structure is a pure fifth interval, but it is not presented in a fifth form]: Chopin, Wagner, Rachmaninov, etc.

B+~ C type [familiar with the law, the core of the pitch organization of the structure is a pure fifth interval, but it is not presented in a fifth form]: the harmonic thinking after impressionism still maintains the traditional composers, such as Ravel and Planck. B+ music maintains excellent listening ability, and harmony is enriched to the greatest extent. Planck is richer than Ravel in the use of single-point chords. So Ravel can be labeled B+, Planck can be labeled C-, and so on.

Class C [familiar with the law, the core of the pitch organization of the structure is the interval beyond the pure fifth degree]: such as avant-garde jazz, piano works by western neo-romantic composers, etc.

C+~ X type [familiar law, the core of the structure's pitch organization is a pure fifth interval, but it is not presented in a fifth form]: Some modern "fearless" composers basically ignore tonality and musicality, but their works are still not completely atonal. Representative examples are some works by Blagi, Einojuhani Rautavaara and Huang Yu.

X-type [familiar rules, the core of pitch structure is not interval relationship]: such as Schoenberg's piano music "Strict Twelve Tones", "Mrs. Hammer" and Utoskaya's Sonata, and so on.
