Church music in the Middle Ages. At that time, church music was sung only by human voice, and no musical instruments were used. The most representative kind of Acabella music is GregorianChants plainsong.

It's true that most of the adaptations of Acabella in China are not good. Even foreign ones are the same. This is often because the arrangement is not good, or the details of the song are not careful enough. In other words, Acabella is not good, mainly because of the poor level. However, this does not change the fact that many works of Acabella are extremely charming.

Some scholars have pointed out that the medieval church music was actually accompanied by musical instruments, which was used to repeat human voices. Therefore, if the word "acappella" means "church-style music", it can also cover music with applied musical instruments, and the instrumental music parts are not independent (that is, only used to repeat singing parts). But today we generally define "acappella" as a chorus that does not involve musical instruments at all.

Although Acappella is not uncommon in European and American pop music, this work form, in which many people * * * work together to simulate various vocal instruments, has become a solo performance by Jason, who independently simulates the sounds of various instruments with his own voice as accompaniment, accompanied by a performance show of strong songs and dances. Such a bold change, even if we look at the global music scene, was initiated by Jason.
