I work with a music teacher/composer in my university, and this question
comes up quite fequently. I think it was for the twelve-tone system.
Listen to any work before Op.11 and some after...the afterworks are written
in 12 tone scale, derrived Mathematically from the 8 tone scales using much
the same formulae of Bach, and modal priciples of 16th centry counterpoint.
To me, it doesn't sound that great tonally, but the sheet music ideas are
very interesting!
