Ask.
What are the basic elements of the generative process? Are there groups of similar elements? Is there a relation between the individual elements and groups?

Know.
All aleatory techniques are based on a theoretically very simple act – the selection and organization of elements from a finite repertoire. The sources of the repertoire may consist of individual items or groups such as words, letters, sound samples, MIDI notes, audio envelopes, color palettes, points, lines, circles, rectangles, images, video footage and the like. Minimalistic aleatory games consist of a single source element, fluctuating games constantly change between two or more sources, and polyphonic games choose from a large repertoire of elements under the premise that no element must dominate.

How.
Determine the repertoire of the generative process and think of possible connections between individual elements.
