You would never hear any song played twice in the same way. The words were retained, but within a certain frame there was great latitude, and the musician could improvise to his heart's content; and the more the variations and combinations, the greater the musician.
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.
Let a short Act of Parliament be passed, placing all street musicians outside the protection of the law, so that any citizen
may assail them with stones, sticks, knives, pistols or bombs without incurring any penalties.
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.
