Nice sonification of OEIS sequences

Show and Tell
#1

As you might know the OEIS (Online Encyclopedia of Integer Sequences) has many integer sequences such as the prime numbers, triangular numbers, digits of pi etc.

I have written a script to sonify those sequences:

In the readme is described how to sonify your favourite OEIS sequence. :slight_smile:
Feedback on this, would be very nice.

Neat! Do you have any sound examples of particularly good sequences you could share?

#3

Thanks Marc,

Yes, I did one with the decimal digits of Pi:

I derived three voices from this sequence. One for Cello and two for Pinao, using different start-note-values and slight different configurations. Then I merged those voices in MuseScore.

How cool! I’m curious: the accidentals really stand out nicely against the very diatonic rest of the piece. How did the Ebs and G#s come about?

#5

Thanks Marc, I use a similarity function to measure how simple / nicely following notes sound, which is based on simple ratios such as 3/2, 2/1 etc. Having defined such a similarity measure, I use the n-nearest neighbors algorithm to draw nearby, nice sounding notes. n is determined by the digits of pi, so in order to answer your question, I would have to reverse engineer this process… :wink: I hope this answers the question a little bit.

Hello,

I like the sonifications! I am trying to get your code running on an M1 Mac and running into a problem where scipy (I think) wants to load a fortran library and can’t find one.

I installed it from here but still got the same error.

Do you have any ideas on this? I’m guessing you ran this on a Linux machine so maybe not…
I might try to do the same…

Thanks

Thanks, You have to install the sagemath package with your linux package manager and probably some additional python modules with pip install. I have done this only on linux and can not say if it will work on Mac.

#8

Yes, I got it to work on Linux. Thanks.
