The following is an excerpt from the 18 page "Analysis of Push or Pull -for Marimba Quartet"

I did in May of 1995

Through the use of certain principles, one can control rhythm

and pitch in analogous ways.  Principles such as circular

permutations, modular arithmetic, and matrixes can be used.

Through the use of modular arithmetic, one can either say that

the exemplified item being moved, is either pushed forward

or pulled backward.  Push or Pull -for Marimba Quartet is an

example of many adaptations to matrixes, set theory, and the

extended use of circular permutations. (as stated above)

        This piece was the first piece that I chose to use controlling principles for the materials. 

It was exciting; the piece went rather quickly!
