"Music came to a full stop with Brahms; and even in Brahms I can begin to hear the noise of machinery" Wittgenstein (1930)
1 Pure Jazz is everything that is random.
(We have input, the program, and output.)
2 What is random, the fact, is the existence of musical facts.
(The input is random within a range, a random choice from a known number of elements.)
3 The musical picture of the facts are the notes.
(The program is the advancement of time with each random choice.)
4 The notes are the significant propositions.
(The notes can be from imperceptible to indefinite. To be significant, they almost always are short or a fraction of short and within a musical range)
5 Propositions are musical functions of elementary propositions.
(An elementary proposition is a musical function of itself.)
6 The general form of musical functions is: MF = random(lower_limit,higher_limit)
(This is the binary form of propositions, the Bernoulli trial)
7 Whereof one cannot make a note, one must make a rest.
