Melody and harmony are like lines and colors in pictures. A simple linear picture may be completely beautiful; the introduction of color may make it vague and insignificant. Yet color may, by combination with lines, create great pictures, so long as it does not smother and destroy their value.
Rhythm and harmony enter most powerfully into the inner most part of the soul and lay forcible hands upon it, bearing grace with them, so making graceful him who is rightly trained.
And this shall be for music when no one else is near,
The fine song for singing, the rare song to hear!
That only I remember, that only you admire,
Of the broad road that stretches and the roadside fire.
For the introduction of a new kind of music must be shunned as imperiling the whole state; since styles of music are never disturbed without affecting the most important political institutions.
