I selected Mozart's Requiem Dies Irae as I feel that it best represents Schopenhauer's understanding of the power of music.  "[music] never expresses the phenomenom, but only the inner nature, the in-itself, of every phenomenon, the will itself. Therefore music does not express this or that particular and definite pleasure, this or that affliction, pain, sorrow, horror, gaiety, merriment, or peace of mind, but joy, pain, sorrow, horror, gaiety, merriment, peace of mind themselves, to a certain extent in the abstract, their essential nature, without any accessories, and so without motives for them... Hence it arises that our imagination is so easily stirred by music, and tries to shape that invisible, yet vividly-aroused, spirit-world that speaks to us directly, to clothe it in flesh and bone, and thus embody it in an analogous example" (261) Music stirs the imagination and thus allows us to be swept away by it and place aside our wills and desires.  As such, music can touch the hearts of many, letting members of an audiece all feel the same emotions in unison as they listen to the same piece. As we listen to Dies Irae, the listener's imagination struggles to form scapes that blend with the music, without the assistance of external images or words.  The listener attempts to grasp at Mozart's feelings as he created this piece, as well as try to comprehend the meaning behind Dies Irae in all its majesty.
