Music directly imitates the passions or states of the soul...when one listens to music that imitates a certain passion, he becomes imbued withthe same passion; and if over a long time he habitually listens to music that rouses ignoble passions, his whole character will be shaped to an ignoble form.
Music is of two kinds: one petty, poor, second-rate, never varying, its base the hundred or so phrasings which all musicians understand, a babbling which is more or less pleasant, the life that most composers live.
Poetry and music I have banished,
But the stupidity
Of root, shoot, blossom or clay
Makes no demand.
I bend my body to the spade
Or grope with a dirty hand.
In Haydn's oratorios, the notes present to the imagination not only motions, as, of the snake, the stag, and the elephant, but colors also; as the green grass.
