De Witt H. Parker, The Principles of Aesthetics
“ Although each tone, as separate and individual, possesses its own feeling in its own right, the tonal effects are immensely accentuated by contrast with one another,—the high against the low, the poor against the rich, the loud against the soft—and through the summation, by means of repetition, of the influences of many tones of like character; the full meaning of music depends upon the relations of tones, especially the temporal relations. ”
