Words of Wisdom

"The interactions of sounds and tones are like
The five colors that enhance each others:
Although they dwell and vanish by no common rule,
And their tortuous, intricate ways permit no liberty,
Yet if a poet masters the secret of change and order,
He will channel them like directing streams to obtain a fountain;
but once a false move leads to reckless indulgence,
The end and the beginning are thrown into confusion,
Celestial blue and earthy yellow confounded,'
