If I understand the Black Box Theory correctly, I should be able to put a set of musical patterns into the black box. This will give me predictable outcomes based on data entered. The more patterns the more predictable the outcome. Am I close?
I've never heard of any mathematical system called "The Black Box Theory". Do you have a link to it? The term "Black Box" is certainly well-known as a general term meaning something whose inner working are unknown. Are you saying that there is one and only one theory for such a device?
The set is correct if it is held as so… within the black box the group is held as so and creates an environment of predictable possible outcomes. If you have two notes or two chords you can create multiple knowable possibilities. When the black box becomes possible the moment of choice will deliver a predictable result, musically.
