“音乐学是什么?” 这个问题，似乎是自明的。 “音乐学”，不就是有关音乐的学问吗?但仔细一想，问题就来了。 如果有关音乐的学问就是“音乐学”，那么，有关表演、作曲的学问是不是“音乐学”呢? 按照“音乐学即有关音乐的学问”的逻辑，应该是。但现实中，有关表演、作曲的学问，从来都是在“音乐学系”之外的其他音乐系科教授的。 “What is musicology?” This question seems self-evident. “Musicology,” is not about the music of science? But a closer look, the problem is coming. If the study of music is “musicology,” then is not music about performance and compositional music? According to the logic of “musicology is about music,” it should be. In reality, however, the studies on performance and composition have always been professors of music departments other than the Department of Music.
