Some whose creativities are confined by all available systems have what
it takes to create a new one.  Why not just write tonal music instead of
searching for what lies outside of it? That would deprive everyone of what
does lie outside of it.  Granted, there are some grey areas on the border
of atonality and extended chromaticism--Wagner, Strauss, Schoenberg, and
Zemlinsky (to name a few) found some great music there.  When all is said
and done tonal and atonal tools frequently don't sound alike, and there's
no point of depriving anyone of the expressive possibilities of the one
or the other.  You can check out the "Agon" and "Canticum Sacrum" by
Stravinsky for great works that use both ends of this spectrum, and you can
see other examples in many of my own works.
