“If poetry and music may be joined, as occurs in hymns, songs, and romances—(though even in these the music does not follow the changes of each verse of the text, as Wagner wants to, but the song and the music merely produce a  coincident effect on the mind)—this occurs only because lyrical poetry and music have, to some extent, one and the same aim: to produce a mental condition  and the conditions produced by lyrical poetry and by music can, more or less, coincide. But even in these conjunctions the center of gravity always lies in one of the two productions, so that it is one of them that produces the artistic impression while the other remains unregarded. And still less is it possible for such union to exist between epic or dramatic poetry and music.”
