Could somebody possibly give a somewhat in-depth explanation on the difference between Fractalized and Formalized composition techniques; I use the term "Formula Composition" not in the broad term that could possibly be understood as any Algorithmic music, but in the serialist form utilized by Stockhausen. Does formula composition tend to restrict less of the piece's variables EG pitch, duration, dynamics and density due to the base parameters being determinate? Because I have been able to find almost no reference material on these two schools of composition, and from the little I have found they sound identical, with the exception of the indeterminacy factor in the base formula of fractalized music, but I assume there are more differences, albeit possibly subtle?
