Famous quotes containing the words cloud and/or base:
“The cloud was so dark that it needed all the bright lights that could be turned upon it. But for four years there was a contagion of nobility in the land, and the best blood North and South poured itself out a libation to propitiate the deities of Truth and Justice. The great sin of slavery was washed out, but at what a cost!”
—M. E. W. Sherwood (1826–1903)
“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.”
—Honoré De Balzac (1799–1850)
