VoronoiDelaunayCircleOfPitchesWithPositiveDefiniteKernel I have been experimenting with number theoretic techniques to get some algorithmic compositions. I use python (mingus) to create the midi, import it on musescore 2 and have the corresponing score.

The method is based on a few ingredients:

  • I use C-major or C-minor and use a symmetric function $f(a,b,c,\cdots)$ and plug in numbers $a,b,c,$ from $1 \le x \le 31$ or some other intervall and compute $f(a,b,c,..) \mod 8$ or $\mod 5$ to generate the pitches.

  • To generate the rhythms / bars, I use a technique to map natural numbers to binary trees (divisorTree, sumTree). This way I have some control over the rhythm fast / slow by plugging in different numbers.

  • In a mixed ensemble I use binary digits to determine at which bar the instrument plays. This creates attention to the listener, so that he/she asks himself/herself, what comes next.

Which other algortihmic techniques from number theory do you know which are used for algorithmic compositions?

Thanks for your help.

Edit: I use e new technique to create a piece of 48 min with 8 instruments and 650 pages scores: (I hope you enjoy:)
