Cellular Automata and Music Using Java 115

Posted by simoniker from the musical-geekout dept.
Justin Powell writes "Take computers, mathematics, and the Java Sound API, add in some Java code, and you've got a recipe for creating some uniquely fascinating music. IBM Staff Software Engineer Paul Reiners demonstrates how to implement some basic concepts of algorithmic music composition in the Java language. He presents code examples and resulting MIDI files generated by the Automatous Monk program, which uses the open source jMusic framework to compose music based on mathematical structures called cellular automata."

      DNA music sounded horrible but it was an interesting novelty. With the right kind of encoding scheme you could probably make something that sounded nice. A friend and I once experimented with fractal music (literally) by writing a script to generate the mandelbrot set in a format that was readable by an amiga-based tracker (OCTAMED). The number-of-iterations (color) value was mapped to pitch and instrument. It was neat because it not only sounded pretty interesting (he tweaked the way the numeric value was mapped to instrument and pitch), but you could also watch the mandelbrot pattern scrolling past in ASCII-form when you hit play. Fun diversion for an afternoon anyway.
      • I actually included fractal music in a game I wrote for the commodore 64 way back in 1984. The game was called Attack of the Galactic Gorillas. I know this risks the chance of getting modded up as funny, but it is actually true!

        As an aside, the music sounded horrible back then as well.

      by jtheory ( 626492 ) on Thursday May 20, 2004 @01:49AM (#9201824) Homepage Journal
      It's not the capabilities of jMusic or the Java Sound API that led them to Java. If you just balance a list of capabilities in the musical realm, there are plenty of specialty languages and environments -- i.e., MAX, PD, ChucK, and so on -- that have greater built-in capabilities, because they are languages or scripting engines focussed only on music. That's also the downside of those languages, though; they are specialty languages.

      In '97-'98 I wrote a bunch of music theory training programs for the Music department at my school (they eventually became this website [emusictheory.com]), and I tried out MAX first before I went with Java. MAX was far better equipped to handle the music-related requirements (anyone remember Java 1.0.2?). But with Java I could put my applets online, run them on any OS, and (biggest bonus) get some serious experience in a language that would get me my first job when I got out of college. Learning a new language to a level where you can tackle an ambitious project is a big investment. There are a lot of musicians and composers with day jobs as developers (like me) who want to be able to leverage what they already have, if feasible. And nowadays, Java has pretty good support for audio, as general-purpose languages go, so many projects wouldn't be giving up much to use Java.

      Here are a few snippets from the jMusic website [qut.edu.au] that suggest why they chose Java for their project:
      Programming in jMusic is programming in Java, not in a meta-language or scripting environment. This means that the full power and cross platform independence of Java is maintained, it also means that the more you know about Java programming the more useful jMusic will be to you. Learning jMusic can be a fun way to gain Java programming skills while focusing on making music.


      [...]Because jMusic has full access to the Java language and support structures, your jMusic work can be as extensive as Java allows (and that is VERY extensive).
      There are more hints at this in the intro of the article, as well.
    • Java provides a wide range of APIs to work with for math, networking and graphics. Cross platform support. The JSyn Plugin [softsynth.com] provides a great synthesis package for making sound, and it can be used with various web browsers. (Linux support is in its early stages.)

    ...might be interesting. Play a note at random, choose a note based on the weighted probability of the next note in a corpus of music, then use the first two notes to figure out the weighted probability of the third, and so on.

    Then if you go out four notes and only one note has any probability of being the fifth in that series, drop off notes from the beginning of the string until there is more than one possibility and continue. Something like:
    1

    123

    (note 5 always follows notes 1234, so drop the 1)
    (1)2346

    (note 8 always follows 23467, so drop 2, note 8 still follows 3467 so drop 3, then there is more than one possible note)
    ((1)23)4679 {etc}

    Then the music would probably sound really familiar, but just about the time you catch on it segues into another pseudo-familiar tune.
    • No, its like this:

      You go out two notes and calculate the weight based on the cosine of the third note. Divide that by the last note of a harmonic frequency. If the note in question is sharp or flat, divide by six and take the remainder. Omit every third note. After the sixth note, if the notes are in fact, collinear and not symmetric, you can reverse the cofactor matrix and restore the eigenvalues, but not without first calculating the modulus of the largest cubic divisor.

    This is cool, but I'm guessing the results won't be very...well, great. Theoretically you could construct every bit pattern for say, 1 MB - 5 MB, capturing the typical encoding of an MP3. Then, you select each byte pattern that sounds good. You would in fact "create" every song that has ever been encoded into MP3 format between 1 and 5 MB. The only problem with this is you are creating more byte patterns than there are protons in the universe, so this is of course practically impossible. It doesn't stop with music either. Anything that can be encoded digitally can be "created" this way. Obviously this cannot happen, not with what we know of anyways, so it's pointless. But it is interesting none the less to think that everything you see, hear, use etc in the realm of digitazion can be created with a simple NFA or graph set to take each "path" and then decode what's viable, etc. Perhaps I should create this algorithm and claim all information withen a certain byte range, sueing for copyright infringment anytime something is created on a computer, as my algorithm has created it already. It's interesting to think about how we get to "create" a finite path in a DFA or byte graph that really already exists, but we need to "find" it.

    Band 1-5: The non-technical types.

    Band 6: "nothing" Engineer (new hires)

    Band 7: Staff Engineer (basically, you get staff in your first few years at IBM unless you're a total moron, and if you DON'T make staff at some point they basically have to promote or fire you)

    Band 8: Advisory Engineer (most IBM engineers spend the bulk of their career as advisory)

    Band 9: Senior Engineer (the fastest I've seen senior made was 10 years, and it's typically 15+ before you get to senior)

    Band 10: Senior Technical Staff Member or STSM (most engineers at IBM never make it this far)

    Band 11: Distinguished Engineer (you have to walk on water and have saved entire villages from destruction to get to this, you basically do whatever you want with a huge budget and work on only the coolest stuff)

    Band 12: IBM Fellow (you are the uber shiznit, report to the execs, and the world is your oyster)

    Look at this as an insight into the workings of the hive mind at IBM. We are the borg, yada yada yada.
  • I'd suggest that interested folks check-out http://www.sseyo.com [sseyo.com] to see a completely different approach to creating generative music, using SSEYO's Koan music engine, which is actually aimed at deploying mobile devices. The site lets Windows users download a plugin/Active X that allows you to listen to some of the interactive sounds/music, and play with the demos, including the awesome "Do The Space Shake" :)

    Another program (written in Java incidentally) which among other things generate music: Grammidity [sourceforge.net]

    It works on the "evolve" principle where you "mate" two objects, and then let either the user or some algorithm decide which of the children are most successful and can evolve further.

  • AI music from the Amiga (Score:2, Interesting)

    Back in the day, there was a weird program for the Amiga computer called "Algoplayer". This program used some crazy AI code to generate random MOD-like songs, based on a seed number. Of course, the genre is techno/house!

    A few years back, I brushed the dust off of my old Amiga, powered it on, and recorded a few good songs produced from this generator.

    I have posted several MP3's of sample output on this website, and some of it rivals some of the garbage coming out of the Dance Top 40 as of late.

    Algorithmic music systems go back at least as far as Mozart. Composers made up algorithms to generate tunes with some sort of randomization (e.g. dice) to make key decisions.
  • Meant to post this earlier--there is a site featuring some pretty cool "algorithmic jazz" pieces by John Clavin here

    http://www.algorithmicjazz.com/

    The compositions (computer programs) are written in Java and use the Jsyn software engine. (Plug in available on the website)

    "The soul of the machine is the collection of algorithms that give it life."

    There are three pieces of varying complexity--mood music for sensitive robots, methinks.
