The article deals with various aspects of justifying music historically. In Matti Huttunen's opinion Western music culture has been strongly historical since the nineteenth century. The article attempts to elucidate the historical nature of music, as well as the canon of music, the selective nature of music history, and the influence of aesthetic conceptions in our views on history. According to the article, the canon contains not only musical works but also other facts of music history. Aesthetic conceptions do not affect only our evaluations and analyses of particular works of music but also our ways of organizing history, including our ideas on causal connections in music history. The only way of escaping prevailing conceptions of music is to go deeper into them; in other words, it requires proper self-reflection.
