„Sweet Power of Music“

Jessica
I am never merry when I hear sweet music.

Lorenzo
The reason is your spirits are attentive:
For do but note a wild and wanton herd
Or race of youthful and unhandled colts
Fetching mad bounds, bellowing and neighing loud,
Which is the hot condition of their blood, –
If they but hear perchance a trumpet sound,
Or any air of music touch their ears,
You shall perceive them make a mutual stand,
Their savage eyes turn’d to a modest gaze,
By the sweet power of music: therefore the poet
Did feign that Orpheus drew trees, stones, and floods,
Since naught so stockish, hard, and full of rage,
But music for the time doth change his nature, –
The man that hath no music in himself,
Nor is not moved with concord of sweet sounds,
Is fit for treasons, stratagems, and spoils,
The motions of his spirit are dull as night,
And his affections dark as Erebus:
Let no such man be trusted: – mark the music.

(Shakespeare - The Merchant of Venice, V, 1, 69-88)
