First of all, in terms of life style, Bach is a devout Protestant. Bach family is a family with a strong religious atmosphere, and its members are basically luthiers or regional deacons in the church. Bach himself is 15 years old in St.; Michael became a church singer and an organist at the age of 18. In his life, except for serving Prince Keton for about six years in Keton, he basically devoted all his energy to the church. Bach himself once said: "Music is a harmonious voice to praise God", and he claimed that all his works were created for God. In this way, we should first approach Bach from the perspective of religion, namely:

1. Bach's works, except the instrumental works written by Keton for Prince Keton, are all created for the church and used in various church ceremonies.

2. Because Bach himself is a devout believer, even the instrumental music he created for the court, its harmonious realm also points to his religiosity.

3. Religion in Bach's music, in fact, it is not the specific religious content that infects us now (such as the lyrics of oratorios, hymns and hymns, etc.). ). In music works, the specific content (such as lyrics) has been expressed through the intermediary of music forms. What we appreciate is actually no longer the content, but the musical vocabulary that the specific content is transformed into through music forms and the realm it expresses. In the intermediary, the actual content such as lyrics has actually become the music itself. To appreciate music, it is important to feel the realm through musical vocabulary, which is an element to purify and sublimate your soul. The musical form and the composer's emotional way together constitute the realm, and the specific content of a work is only its creative background. In this way, if you stay on the basis of listening to the content, you are likely to listen to literature or something else, not music. Secondly, from the music itself, Bach is a master of polyphony. On the basis of the musical expressions pioneered by his former masters, he tried to enrich and simplify them. He developed the counterpoint and variation of polyphony most abundantly, making polyphony music "incomprehensible" (forming a complex hierarchical order, making people feel infinite in infinite changes), simplifying the expression of phrases themselves and phrases, and simplifying the structure between phrases. The richness in simplicity and the simplicity in richness are all based on extremely high skills. In this sense, Bach's technology is superb, and we should listen to the charm of his technology itself. To hear the charm of technology itself, we need to understand the basic elements of polyphonic music.

In Bach's music, apart from religious factors, we should not pursue the meaning of his works too much from music. In Bach's era, music served religion on the one hand and aristocrats on the other, and music was often a form of service. In Bach's music, even if there is a title, it is often not the bearing of specific content. Therefore, to appreciate Bach's music, we should not try our best to find personal situation and actual creative content when composing music, just like Beethoven. Nor should we try to find the interweaving of inspiration and emotion in music as we appreciate Mozart. The charm of Bach's works is not only the devotion to God, but also the pursuit of music creation itself. The real charm of Bach's works often lies in its handling of rhythm, the change of its phrases in the counterpoint cycle, and the structure established in the position and change between points, lines and lines.
