Flux is structured in the following manner: two outer sections of mainly static material framing a middle section of more rapid writing. The two outer sections were formulated using calculations to determine the frequency of Ion Flux; the photon opening angle of an individual electron as a function of the device critical energy convolved with the electron beam divergence. The resultant pitches were calculated by taking readings of photon energy at certain points on the graph, and then their frequencies calculated and converted into pitches within the nearest quartertone.

The resultant pitch sequence is heard in their entirety during the opening and then subjected to manipulation at certain points throughout the work and the resultant harmonies also produce various states of frequency oscillation which are another primary concern of the work. The work also uses various serial techniques but it is the mathematical principle that was the chief aspect involved in the compositional process.
