Music as literature

we can 100% say that music is literature no doubt. To define literature its just as simple as writing words on a paper and making something out of it. The difference between a novel and a rap is a novel is book and it doesn't  have the same meanings as a rap does. The difference between a poem and a song is not really anything because a poem is a song and a song is a poem a lot of writings are poems.  The difference between an opera and a symphony is that a opera usually has singing and acting and a symphony does not.
