Arthur Edward Johnstone,
Instruments of the Modern Symphony Orchestra…
(1917)
“ Not only is the orchestra capable of rendering at one time a multiplicity of independent themes, but by virtue of the many different tone colors which characterize the various instruments, the melodic line traced by each individual voice may be easily followed by the attentive ear, while all the voices blend in one harmonious whole. It is this complete independence of each voice in respect to power, tonal quality, and style of phrasing which makes the orchestra unapproachable as a means of musical expression. ”
