for music always expresses only the quintessence of life and its events, never these themselves, and therefore their differences do not always affect it.

Context

“This is the origin of the song with words, and finally of the opera, the text of which should therefore never forsake that subordinate position in order to make itself the chief thing and the music a mere means of expressing it, which is a great misconception and a piece of utter perversity; for music always expresses only the quintessence of life and its events, never these themselves, and therefore their differences do not always affect it. It is precisely this universality, which belongs exclusively to it, together with the greatest determinateness, that gives music the high worth which it has as the panacea for all our woes. Thus, if music is too closely united to the words, and tries to form itself according to the events, it is striving to speak a language which is not its own.” source
