Seattle, March 2009
“If we wish to use tempo as melody, we have but to establish the tempo value of various tones, and change them as the piece progresses…
This use of consecutive changes of tempo is of course no new thing; it is the mathematical ratio between tempi that has not been systematized. It can be observed in current practice that when the relations between successive tempi do not follow a simple ratio, but are accidental and arbitrary, the result is felt to be rhythmically rough. Conversely, I am convinced that further investigation would confirm my own experiments, which show that when successive tempi…. Give an impression of smoothness, [the] ratio … is demonstrably simple.”

“Carl Ruggles has developed a process for himself in writing melodies for polyphonic purposes which embodies a new principle and is more purely contrapuntal than a consideration of harmonic intervals. He finds that if the same note is repeated in a melody before enough notes have intervened to remove the impression of the original note, there is a sense of tautology, because the melody should have proceeded to a fresh note instead of to a note already in the consciousness of the listener. Therefore Ruggles writes at least seven or eight different notes in a melody before allowing himself to repeat the same note, even in the octave.”
Henry Cowell, NMR, pp. 41-42
“Avoid repetition of any tone until at least six progressions have been made.”

“I believe that what he was primarily concerned with was freshness — newness, maximal variety of pitch-content — and the sustaining of a high degree of atonal or atonical (but nevertheless harmonic) tension.”
James Tenney, 1997. “The Chronological Evolution of Carl Ruggles’ Melodic Style”
Tenney: Chronological graphs of ALSD, ALSCin Ruggles’ works(average length of different pitch classes; average length of consonant pitch strings)
“Consider for a moment what is meant by the incredibly high values for ALSD reached in Sun Treader, the Evocations, and Organum. It is, in each case, almost 9, which means that at every moment in the process of composing these melodic lines there were only four pitch-classes remaining to chose from for the next tone — and not even all of these four would necessarily satisfy certain other conditions, such as the desire for dissonant relations in close proximity. Very severe constraints indeed, for a music which sounds so free!” (Tenney)
“Along with backtracking, statistical feedback is probably the most pervasive technique used by my composing programs. As contrasted with random procedures which seek to create unpredictability or lack of pattern, statistical feedback actively seeks to bring a population of elements into conformity with a prescribed distribution. The basic trick is to maintain statistics describing how much each option has been used in the past and to bias the decisions in favor of those options which currently fall farthest short of their ideal representation”

1. Take N elements and associated probabilities pn
2. Using a pseudo-random number generator, pick an element
3. Set the selected element’s probability to zero (or some very low value)
4. Increment all other probabilities by some uniform or weighted amount
5. Pick again
