Pure music is music whose original intention of composition does not include lyrics. This music mode expresses the author's emotions completely with pure and beautiful music, so it is generally called pure music. It has no lyrics, but it can embody the wonderful artistic conception with its own beautiful melody. However, it should be noted that the concept of pure music is to distinguish music with words from music without words, rather than saying that music with words is miscellaneous music. After all, vocal music is also a form of music.
