"I am fully convinced (that), if music be not allowed to grow,
if it's denied the privilege of evolution that all other arts and life have if (in the) natural processes
of the ear and mind it is not allowed (to)
grow bigger by finding possibilities that nature has for music,
more and wider scales, new
combinations of tone, new keys and more keys and beats, and
phrases together -if it just sticks (as
it does today) to one key, one single and easy rhythm, and the
rules made to boss them - then
music, before many years, cannot be composed - everything will
be used up - endless repetitions of
static melodies, harmonies, resolutions, and metres - and music
as a creative art will die - for to
compose will be but to manufacture conventionalized MUSH..."

-Charles Ives (1874-1954)
