Western tonality has some rules. Composers can operate outside of that if they want. With computers, a single composer could make up a new set of rules for every piece. You can turn a drum beat into a note by accelerating the wave form, invent your own scales. It is interesting that even electronic artists tend to operate within the constraints of the western tradition. It is probably a struggle to find an audience o…
