Introduction to classical music:
CLASSICAL MUSIC, translated into Chinese as "classical music", some people think that "classical" feels antique , old-fashioned taste, so it was renamed "classic music". Some people also call it "serious music" based on the definition of classical in the Oxford English Dictionary, in traditional and serious style. As a result, "classical music" has been labeled as "serious" again, making people even more afraid to approach it.
But the person who made this definition must not have looked up the dictionary carefully, because the second meaning of serious is defined as follows: (referring to books, music, etc.) to inspire thinking, not just for entertainment. Therefore, we know that the original difference between classical music and popular music is that it has profound connotations, can make people think deeply, and can make people noble and avoid vulgarity.
