Mathematically Pattern-Free Music

gary.flake writes "'Scott Rickard set out to do what no musician has ever tried — to make the world's ugliest piece of music [video]. At TEDxMIA, he discusses the math and science behind creating a piece of music devoid of any pattern.' He used mathematics of Évariste Galois (who was born 200 years ago) to create pattern-free sonar pings which he mapped to notes on a piano, and then played them using the non-rhythm of a Golomb Ruler. Now, why didn't I think of that..."

To find all 30-by-30's will take 5 times longer; Each time we increase the size of the array by one, it takes about 5x longer to enumerate the space (don't know why that's the case). So, needless to say, we're going to have to wait a while to find even a single array of size 88-by-88 by brute force search.

    But again, that's creating a pattern by using the patternless super pattern. So that wasn't the point of the exercise.

    There is a term used by some of the improvisers, the "endless melody" or the "open line". Eric Dolphy and Claude Debussey called it the "unending line".

    It is the unfolding melody, not repeating, that goes from here to there without any repeating sections. I'm tired at the moment, so all I can think of is some of the work of Jimmy Giuffre or Paul Bley, but there have been many others. In the classical tradition, LaMont Young and Arvo Part.

    As I'm sure you know, human beings when presented with random data will work overtime to find patterns, even imagining them. It's what our brains are made to do. It's one explanation for religious belief and superstition. So the question becomes, if your viewer/listener is going to impose a pattern anyway, why not give him some to work with?

    I remember early on being a theoritician, thinking that there was more value in this kind of exercise that this article describes than was really there. I've become more leery of theoretics the older I get, which became a problem since my area of professional expertise was in literary theory and critical theory. Now I care more about something that touches the part that is sometimes called "the soul". Instead of art which instructs, I seek art that moves one, or exhorts, or comforts, or simply celebrates. That doesn't mean it shouldn't challenge, but never at the expense of a human connection.

    OK, it's my bedtime now. I've become fully incoherent. Sorry.

  63. "Applications" of math by OeLeWaPpErKe · · Score: 2

    Actually it's "useful" in the way mathematics stuff is always beautifully useless. You see, if you wanted to do echolocation with a piano (or any other 88-note instrument), this would be the piece that gave you maximum information on the target.

    http://en.wikipedia.org/wiki/Animal_echolocation#Acoustic_features

    Believe it or not, if you played this music often you would (after a loong time) become able to hear the differences in the room the music was played in, just by the sound.

    Bats use this to accomplish something that seems implausibly difficult, some species use it to dive through moving branches composing the upper level of a forest, in the dark (and they're blind or near-blind anyway), filled with environmental sounds and general noises, at ~ 180 km/h. When stationary they can use the tones to see through walls, and tell from the outside if anything in a room or cave is moving or not, including the rhythm of it's movement.

    Actually, it's not only music a mathematician could have written, it's also an interpretation only a mathematician could reach. In contrast to what this guy calls perfect lack of repetition the music doesn't lack all repetition. It merely lacks a very distinct property. As I understand it, the special thing about that piece is that not any two subsequent notes differ in the same amount of frequency. Analogous the rhythm. So first of all are trivial and obvious patterns of repetition left: e.g. you will find many times two notes where the second is higher than the first. Or you will find passages, where the tones are de- or ascending, maybe even tied with a similarly shaped rhythm (think of relatively fast or slow sequences). And then there are also properties of sound, which cannot be expressed in formal languages as in modern musical theory. In fact, I would argue that there kinds of music in the world, whose point cannot be expressed by classical formal musical theory. The takeaway or the crucial perspective should be here, that your listening to music is always an act of construction. You will read sense or pattern or intention or whatever you want into music, depending on your socialization, your mood or your capabilities. People will tend to simplify more complex phenomena by means of more general concepts (high following high instead of the actual and precise note pitch and so on). So this interference of mathematics is not so provocative after all. If you can't find a point in this music - fine. But that does not depend on a single and not even most prominent mathematical property.

  70. Beauty is also in "swing" by meteormarc · · Score: 1

    Much of the beauty of music is in the way it is played. The piano player in the TED video was so kind to take the music seriously and make the best of it, i.e. suggesting structure by subtly varying the duration of notes relative to how they are written in the score. The piece would be much uglier when converted into a midi file and played automatically on an electric piano.

    Well, different branches of mathematics have different notions of randomness. Your post makes sense assuming a statistician's concept of randomness. Your parent post almost makes sense assuming an information theorist's concept of random. (I say almost because actually proving a sequence to be Kolmogorov random is an incomputable problem.)

    Spectrograph is a word that will help, as that's a picture of the sound made by running the raw audio (usually WAV) through a n-band FFT and representing the data as an image. I remember using some software back in the late 90s that was designed to do the opposite, and creating a few short samples from interesting parts of the Mandelbrot set. I don't remember what software I used, and while the computer I used still works the hard drive has been formatted so many times I doubt any trace of it still exists. But google turns up asperes, which looks to do what you want. AudioPaint looks very similar to what I once used, as it uses the color of the pixels to tweek the left/right panning, allowing for more than just a 2D sound.

    What I learned back then was that pretty pictures tended to make very horrible sounds if allowed to play for any long amount of time (more than a second) but that they made really interesting drum samples and sound effects. Uninteresting pictures could sound very beautiful in both the short and longer time ranges.

  73. Re:Pretentious by Qhartb · · Score: 1

    I agree it's not really accurate to call it "The World's Ugliest Piece of Music." That would imply that the beauty of music is solely a function of how repetitive it is, which is obviously false because a single note repeated at regular intervals (or maybe a square wave held indefinitely on a single pitch) would certainly not qualify as "The World's Most Beautiful Piece of Music."

    However, I don't mind this as a bit of marketing. There's really no denying that this piece is intended to be listened to after a brief explanation of the mathematics behind it, and "Mathematically Ugliest Music" is a more intriguing hook than the more descriptive "equally-tempered 88-tone row without repeated pitch or interval classes, played so that no two notes are rhythmically separated by the same rhythmic distance, on the premise that repetition is necessary for beauty in music."

    While this piece does minimize a positive aspect of music, it does nothing to maximize negative aspects. Dissonance counterpoint comes to mind as a better example of actually trying to write unpleasing music. Basically, it takes the rules of counterpoint theorists have used to describe the music of Palestrina or Bach, then slavishly follows the opposite of those rules.
