chance determines all sets to a large extent
the interplay of 3 and 4

3 main structure — 4 sided symmetry — 4 movements
3 structured 1 chance
3 fast 1 slow

no more than 7 elements at 1 time — sets on sets — each set works itself out

length on screen determined by choice or chance

4 colors used no more than 3 at a time
or 7 colors no more than 4 or 3 at a time
determine first sets by choice — choose starting point and work from there
max of 4 structures in any given color
pick similarities to carry from movement to movement to establish continuity
superficial knowledge of set theory and 12 tone structure

trying to read Babbitt but can’t

20 element sets?


more problems with program — have to write it out so I can work on it at work etc — want to get that done — need to sleep less — maybe able to get some printed forms
