    I was honored to have studied with prof. Forte. It is necessary to add three facts to this fine introduction: 1) Set theory offers insight into super/sub set relations within ATONAL and MODAL structures not just 12-tone. (This is how to progress in analysis of larger pieces of music) Master Forte already in the 90ies combined Set theory with schenkerian approach in observing the counterpoint and marginal pitches within atonal or modal texture. (Set theory serves us to ANALYZE and LISTEN with good knowledge of the material) 3) Interval vector information offer an incredible tool for composers: I call it THE GOLDEN RULE of invariant pitch classes under certain transpositions or inversions (two rules, actually). And, the interval vector accounts also for the INVERSIONS of interval classes: m2/M7, M2/m7 etc.(also, the set-table offers a comprehensive overview of ALL possible complementary sets within 12 tones!). I wrote my doctoral thesis (DMA) on Messiaen's harmony (Harmonic Density in Messiaen, Cornell 99', mentor R. Sierra) precisely with set theory tools. In Messiaen's bibliography (I think by Vincent Benitez) my last name Savli is misspelled into Salvi. (dyslexia not allowed here!)

      It's still very cool! I mean pitch classes look exactly like Z/12Z, interval classes are exactly a discrete metric on the pitch classes (given a 0 IC) which makes then have some sort of topology. I'm a sense Z-relationships are exactly given by modding out by an equivalence relation (namely two subsets of the set of n tuples of pitch classes are equivalent if their interval vectors are the same. I'll leave this to the reader to verify that this is indeed an equivalence relation) . It's very algebraic and topological feeling; hence quite familiar. It's lovely

    Fun fact about those all interval tetrachords 0146 and 0137 as they relate to tonality:
    If you think of 0146 as the scale degrees of the harmonic minor scale you get #7, 1, 3, and 4 (I.e. G#, A, C, and D). If you think of 0137 as the scale degrees of its relative major scale you get scale degrees 3, 4, 5, and 7 (I.e. E, F, G, and B). That’s all 8 notes of the major/relative harmonic minor scale (aka the “bebop scale”) appearing once and only once.
    Just goes to show how colorful the good old fashioned major scale really is.

    i just recently finished up my general music theory studies, and set theory was by far my favorite part. it also resonates with me greatly because my musical background comes from chiptune and demoscene, which are usually written in programs called trackers. trackers actually make use hex values, and as a result one actually ends up thinking about and applying intervals in terms of set theory. the music is vastly more tonal in these circles so its not serial by any means, but its a fun parallel that made learning set theory enjoyable for me.

    I was at Eastman when Howard Hanson wrote the book that supposedly initiated interest in this approach. Although I majored in music theory, I didn't understand it then, and I don't understand it now. However, I have no doubt at all that it's a legitimate and significant contribution to music analysis.

    • @charlesmoomaw9388
      @charlesmoomaw9388 8 месяцев назад

      Hanson's classification method is similar to set theory's interval vectors. Hanson classified chords according to their PMNSDT, i.e., the number of Perfect fifths, Major thirds, miNor thirds, major Seconds, minor seconds (Dissonances), and Tritones (or their inversions, reduced to the same octave) contained in a chord. For example, major and minor triads are both PMN, the quartal harmony C-F-Bb is P2S (C to F and F to Bb are both P's, hence P2), and a major/minor seventh chord is PMN2ST. A set theory interval vector counts intervals in the order m2, M2, m3, M3, P, and T, and it uses zeroes when a particular interval is not present, so Hanson's P2S is the same as interval vector [010020], and PMN2ST is the same as interval vector [021111].

      16-TET is similar to 12-TET in that it can be conceptualized as a set of four non-overlapping diminished-seventh chords (i.e. the 0369 set) as opposed to the three found in 12-TET. So it basically splits the minor third into one more part, which ultimately doesn't gain xenharmonic composers a whole lot. 17 is very creepy to my ear; I did some experiments in that temperament for a choreographer some years ago and she was spooked at the result so much that we scrapped it (much to my chagrin).

  • @nartoomeon9378
    @nartoomeon9378 Год назад

    I can say that an interval vector looks like a simplified notation of a multiset ( set with repetitions) of interval differences. Is like an uncommon operation called Minkovski sum or substraction, but repetition is considered. We calculate intervals by subtracting pitch classes. Then, we group by some standard value of intervals, and make a formal sum as products of those intervals by the number of repetitions for each.
    I couldn't figure out for days why the backward motion is taken into count. But then I realized that the distance usually is |a - b|. But in modular math (-a = 12-a) So if (3 - 5 = -2) then
    (-2) = 10 mod(12). *In terms of integers |-2| should be 2, not 10.* This is the reason for the mutually inverted series being undistinguishable in this system. I think I'm right...
    But I don't like it... Inversion doesn't save the chords, most of them. The direct connection of regular and negative harmony does not seem pleasant to the ear. Matching interval vectors for different series seems unlikely to be a good thing. Maybe I don't know the main tasks for which it was created and therefore I don't see any perspective. I'll do a post later with a more interesting problem with some related concepts.

    • @ClassicalNerd
      @ClassicalNerd  Год назад +1

      I think you're coming at this from a more mathematical angle, while music theorists adapt concepts in a more fast-and-loose style. The modulo-12 thing usually screws with people not used to it, but it works and is self-consistent.
      IC vectors are useful, but in a pretty limited sense. Elliott Carter's music, for instance, would not sound the same without his favorite all-interval tetrachords, and its unique properties are best shown in the IC vector. It also shows Z-relations pretty well. Since this is an analytical system for atonality, the goal isn't to preserve audible tonal relationships (inversion working totally differently in atonality than it does in tonal theory) or to be "pleasing" (which is highly subjective).

      @@ClassicalNerd We could agree with that, because music is, after all, about a man. It is the human who finally decides which music is good and which music is bad. I have long thought that music was able to go the other way because of people. And harmony is mostly a habit. Maybe the tritone sounded very dissonant in the past indeed. But now it's everywhere. Still, I'm not sure that psychology answers all questions about music.
      I'm sure theories can be constructed in different ways, depending on the goal. You don't have to calculate everything, you can build a theory about a *way* of calculating, for example. ✨
      So I came to questions like this: Can humans get used to non-classical scales? (Relate dissonant intervals and chords to some emotion.) Maybe one should look for some structural properties of the scales, softer than the carefully and precisely tuned ones, as in JI?
      I already have a suggestion for what that might look like, but the message lines are too narrow for it. )
      ✨From lectures by a very high level algebraist, I heard a criticism of his direction(homological algebra, etc.): "in recent years, constructions have been replaced by constructors".

    The irony in this is that this way of thinking about music is probably closer to the way a lot of musicians who “don’t know music theory” approach it than traditional Roman numeral oriented theory. Which intervals apart of notes or particular chords sound good, as opposed to triadic groups in particular keys. Like, describing music as 0-1-3-6 or something similar, that looks like guitar tab, the way of reading music for guitarists that don’t know the “proper” way of reading music. Of course, that’s only a 1 to 1 if the open string in question is the root note, but it has similarities in that the tab would look identical for a song in D in D standard tuning as it would for the same song in E in standard tuning; the relative intervals on each string remain the same, even if they’d be completely different notes and key in traditional sheet sheet music.

Tonal theory completely kicked my ass, while all of the 18-year-olds in my classes breezed through it effortlessly. When we got to post-tonal theory, the script was completely reversed. Not only did set theory make 100% sense to me, it was actually how I had been visualizing music in my head all along.

This video would do a lot better with audio examples, but we're at past the 20 minute mark on a very imposing subject as it is. It is historically limited by being anchored to serial music, but I think there's an untapped potential here for a much more powerful generalized framework.

      I would argue that few (if any) analytical frameworks make predictions about how we perceive music. Generally they form either a lens through which listeners can come to better understand and appreciate a fundamentally aural experience, or a toolbox for composers to construct music in a way that has a logical underlying structure. In this case, the listening experience is recontextualized as a mathematical one using set theory, while its biggest functional use is for composers seeking to write self-consistent atonal music without either throwing all caution to the wind or using a 12-tone system.

      but that does not make the linguistic theory of how to form words from letters that refer to some componist or a biblical verse a theory of music
      same goes for any theory about the non-musical phenomena that inspired xenakis music - it may be a theory that inspired music and that helps us understand music inspired by that music, but it's not a theory of music
      I think music is first and foremost a perceptual phenomenon (ignoring cultural aspects) and hence a theory of music should explain musical perceptions like dissonance or a sense of direction etc and isn't this exactly what a concept like leading tones or the harmony of Helmholtz, which is rooted in his theory of our perception of complex tones, are trying to do?
      to be fair - this is basically all I know about music theory, and it's all geared towards tonal music. maybe a theory of non-tonal music could look somewhat like the ligeti-video david bruce uploaded today, describing and explaining phenomena like recognition of motives that play an important role in non-tonal music as well in analogy to visual perception or in terms of psychological concepts like gestalt
      I don't wan't to arrive at the conclusion that all music theory that is not basically neuroscience is invalid though, Ill have to think about all that some more...

      I'm not sure we're approaching some of these terms from the same point of view but it's a fascinating discussion to have nonetheless!
      From a compositional perspective (which is where I come from), analysis is a tool that peels back the perceptual layer to something more concrete. In particular, set theory is just an approach towards naming and labeling harmonic or melodic motifs, which is why it means nothing in and of itself; one must be judicious in segmenting the music into sets that make contextual sense and then look all over the music to find other incarnations of the same or similar set. If the perceptual phenomenon is something akin to-in an atonal/serial piece, for instance-hearing something that has no discernible form or structure and yet still feeling as though the piece is something of a unified whole, set theory might be something that could help explain the details as to why it might be perceived that way.

    I am really sorry, the school computer has been glitchy all day: (. So if you just got a bunch of dislikes on this video, they are regretfully from me by accident.
    I actually LOVE this video, and I am going to try counterbalance with a bunch of likes!!
    Sorry, keep up the great work : )

      No worries! Most dislikes, according to my analytics, are from people who don't watch the videos at all or they're a side effect of Thailand-based bot farms. They're incapable of substantive critique, which I'm open to! (By the way, RUclipsrs have no way of knowing _who_ likes or dislikes a video, and most of us don't really care-either one boosts engagement, which is a plus!)

      @@ClassicalNerd Group theory is invoked, but in a fairly rudimentary way, in alot of 12 tone & set theory, in the sense that the integers mod 12 form a group under addition, & the transposition & inverse & retrograde forms of a row form groups. Are you aware of the cycle of 5ths transform as multiplication by 5 or 7?

    It is a shame so many people believe music has to be simply an expression of beauty as mathematical music is a taboo. But music at its core is just wiggly air and can be whatever the composer fancies.

    Is understanding the set theory like tuning your own piano? Either way, watched it to the end with pleasure. Also, you're getting closer to having your face in focus.

    • @ClassicalNerd
      @ClassicalNerd  4 года назад +2

      Tuning an instrument is its own can of worms to which I'm not sure set theory would be very helpful. Also, my poor camera is really not designed for any of what I've put it through, and to be honestly, sometimes I'm just happy it turns on. (You're more than welcome to buy me a new one if you like.)

    Isn’t it Allen For-tay and Alberto Ginastera Heen-ast-er-ah? Outside of your pronunciations, (a problem with most of your videos) your presentation was quite clear and well organized.
    The Forte book is rather frustrating. Forte himself made many mistakes and the book is littered with them.

      The theory professor who taught me this actually studied with Forte. So I would say the pronunciation of that is as accurate as I can make it.

    Wow that was really interesting, I've never heard of it before and surprinsingly I reached some similar conclusions a while ago when I tried to summerize in a equation how intervals could be inverted. I did that just for fun because of something that the teacher of my music theory class said got me thinking of it, but I stopped working in that project eventually.

    I'm a mediocre composer on too many instruments, including guitar, and I have a mathematical bent. To me, counting in numbered semitone intervals feels quite natural. Mapping intervals onto integers feels natural to me; integers have quality I'll describe as flat, homogeneous and/or uniform, without defining further. Note that unlike a piano, a guitar has no "black frets".
    For those who found it interesting that the 0146 chord had '1' in every interval, you may be interested in Golomb ruers, see en.wikipedia.org/wiki/Golomb_ruler.
    I don't know if they're explicitly mentioned in this TED talk, but if you like the interface of music and wonky math, you may enjoy ruclips.net/video/RENk9PK06AQ/видео.html.
    I have never fully understood the function of developing a conceptual apparatus in order solely to analyze a piece of music: it seems iike the result of the analysis always gets stored in write-only memory. At least when I did it in school. This video contains an interesting semi-implicit claim: that interval vectors can in general be used to predict when chords sound similar-suggested by the application of this general idea to the specific case of 0146 vs. 0137.
    Hm. I guess I'll have to mull that one over. Also, I guess a minor vs. major chord sound relatively similar, compared to a diminished or augmented chord or a 7-chord or [insert any amount of frills here], even though major/minor is simultaneously a rather (ahem) key distinction. [Pun not intended. At least not at first.]
