  • What's a negative time signature? Well, it's not really a thing... yet. But Adam Neely made a video about the possibility and what it could mean to write music in -4/4 time, which got me thinking about other possible answers, and I think I've come up with something I really like so I thought I'd share. Plus, a little youtube drama never hurt anyone, so why not start a fight with Adam?
    Seriously, though, his answer was good too. But still. Fight!

    Neat idea! I do like your approach, although honestly, I think the whole thing is...not super useful in any serious way, because there are already other ways to think about the subjects we offered for a "negative time signature." That said, feuding and meme theory gets the clicks, so lets fight!!!!!

    • @12tone
      @12tone  6 ปีที่แล้ว +694

      Yeah, in the end I don't think there's ever going to be a serious answer that actually needs negative numbers in order to work, for basically the reasons you stated in your video. Still, though, looking at weird questions is a great way to find unusual parts of music to explore, and I'm glad I went down this rabbit hole 'cause it got me thinking about systematized backmasking, which I'd never really considered before, so thanks for the inspiration!
      Man, I'm really good at fights, I should get into them more often.

    If you write half of your song in 4/4 and the other half in -4/4, does it cancel out and leave no song?

    • @FacePomagranate
      @FacePomagranate 6 ปีที่แล้ว +26

      Well you'd be reversing the -4/4 which would make it positive, so actually you'd end up with the song being twice as long.

      Music is not observed as a finished product. Let me use a number line as an analogy. Technically, yes, youd be going forward 4, then backwards 4, ending on zero, leaving you with no change. But music isn't just looking at the dot on the zero. Music is watching the dot moving from the zero, to the four, and back to the zero. It's watching change over time, even if that change just gets you back to where you started.

    Negative 4/4 is the rhythm that happens before the composition begins, such as a metronome, clearing your throat, blowing your nose, reaching for some tissues.

    Wouldn't a reversed recording be negative tempo, not negative time signature? That seems more natural to me.

    • @Error404fucknickname
      @Error404fucknickname 6 ปีที่แล้ว +61

      Simon The Human well, the notation says that every black note equals some positive rythmic unit, so
      Negative time sig*Postive rythm=Negative play speed
      Positive time sig*Negative rythm=Negative play speed
      So yeah, i think both work? Lmao

    • @DampeS8N
      @DampeS8N 6 ปีที่แล้ว +31

      Have to agree. Neither idea of what a negative time signature is is very satisfying to me, though I think Neely's is more accurate as a reversal of the measure's impulse and not the whole composition.
      In the end, I don't think the concept is very useful either way. And I can't come up with a way it would be useful unless it had exotic contextual meaning similar to how symbols in math can mean things that have nothing to do with how they are traditionally used - they are just stolen and re-purposed.

    • @rgbplaza5945

    • @12tone
      @12tone  6 ปีที่แล้ว +59

      Good point! I was mainly thinking of it, though, as a polymetric device, to be used for individual parts within a larger, positive composition, in which case I think it's better viewed as a change in rhythm than a change in tempo. Not sure, though!

    • @vincentnydam
      @vincentnydam 6 ปีที่แล้ว +1

      Bone Machine by The Pixies sounds to me like the drums are in -4/4 while the vocals are in 4/4. I hear Adam Neely's 'reverse of the accent pattern'-or rather a differing accent pattern-between the drums and vocals. The drums accent beats 1&3 while the vocals accent beats 2&4. To me the verse is in -4/4, the refrain combines -4/4 rhythm section with 4/4 vocals, and chorus is in 4/4. Whadyu think? th-cam.com/video/yJM576_1UX4/w-d-xo.html

    I happened to transcribe reversed pieces of music (such as Metallica's Damage Inc and Blackened intros, or my Gone Too Far's outro), and it was a tricky thing to do. Simply writing them forward and leaving a note "play it in reverse" didn't satisfy me. Perhaps, 12tone's interpretation of negative time signature could make that more accurate in a way. Anyway, I may not judge you guys, since I suck at music theory)))

  • @AlanKey86
    @AlanKey86 6 ปีที่แล้ว +106

    Awesome video 12tone.
    My objection to the scheme proposed by Adam is that it doesn't follow arithmetic rules. Namely, a bar of 4/4 followed by a bar of 2/4 could be notated as a single bar of 6/4. But a bar of 4/4 followed by one bar of -2/4 does not equal a bar of 2/4.
    Like any of the worst critics, I raise this objection without having a constructive response of my own. The only vauge thought I had was the idea of inverting a waveform and playing it at the same time as the non-inverted waveform so that they cancel out. But even this isn't subtracting time in the way that I think negative time signatures ought to do.

    • @12tone
      @12tone  6 ปีที่แล้ว +18

      That's a great point, and it's one my solution doesn't really address either! There's not really a clean way in my system for a part to switch from a positive to a negative time at all, so it doesn't directly create those sorts of contradictions like Adam's does, but there's no real equivalence to the arithmetic relationships that real positive and negative numbers have. Although...
      If I had a part written in, say, 4/4, and I inserted a bar of -2/4 at some point, it would make sense to, in editing, take that section and reverse it back through the bar before it, so that it ended on beat 3 of the previous bar. That creates some problems with the next forwards component, which would then overlap the original, but you could use that to create layering, like an ensemble produced out of one voice that snakes back and forth through time... Neat!

    • @Livingeidolon
      @Livingeidolon 6 ปีที่แล้ว +6

      But arithmetically speaking a negative sign simply means the opposite of. The opposite of having one thing isn't not having a thing, it's owing a thing, right?
      So, mathematics would say that your example of 4/4 followed by - 2/4 would indeed be felt as 2/4.
      The reason why that's nonsensical is that time signature doesn't work like math. 4/4 followed by 2/4 could feel like any number of subdivisions of six pulses divided into quarters.
      Man I don't feel like that's clear, but my break is over.

    • @TheViolaBuddy
      @TheViolaBuddy 6 ปีที่แล้ว +4

      On the other hand, a bar of 2/4 followed by a bar of 6/8 might not feel like a bar of 10/8; it might instead feel like a bar of 4/4 but subdivided as triplets in the latter half (it depends on if there's the "♩ = ♩." marking or not). And in general something like 3/4 does not feel the same as 6/8 even though they're the same fraction. Heck, 6/8 doesn't even feel like six beats; it feels like two. So there are already some oddities about time signatures.

    • @yoverale
      @yoverale 6 ปีที่แล้ว +7

      Good point, then we should answer first what is a 0 (zero) time signature in a musical context.
      4/4 bar = 1 = a whole note
      -4/4 bar = -1= a negative whole note (?)
      Then 4/4 - 4/4 = 0 bar ... does it have any meaning to you?

    • @Livingeidolon
      @Livingeidolon 6 ปีที่แล้ว +1

      Ale Lloveras see that's where I got stuck on at first. But the negative sign doesn't change the number, per se, it changes the concept attached. That's when I started thinking that - 4/4 would mean change the rule from four pulses and a quarter note to anything but that.

    • @scottblair8261
      @scottblair8261 5 ปีที่แล้ว +2

      My major concern with imaginary time signatures is that there is no way of multiplying time signatures. You can add them, and multiply by scalars, but time signatures are not scalars. You can't multiply 2/4 by 4/4. At least there is no clear way to do this. I disagree with the solution in the video because it doesn't comply by time signature arithmetic 4/4-2/4 is not 2/4 by this definition.

    Additionally, the bit on backmasking reminded me of the intro to the Electric Light Orchestra’s “Fire On High” from their Face the Music album. There’s a backmasked message where Bev Bevan says, “The music is reversible, but time... is not. Turn back! Turn back!...” It’s an interesting message, especially in the context of this video.

    "Ma Fin Est Mon Commencement" composed by Guillaume de Machaut is an earlier example of reversible music from the 14th century. It is 3 lines of vocal music. The second line is the retrograde of the first line, and the third line is the retrograde of itself. Just an extra factoid about music in reverse. Great video.

    If you haven't heard it, Miracle Musical's "The Mind Electric" is a song that's played backwards first, then forwards, lyrics and all. It's interesting because while you're listening to the first part you get a sense of this musical theme that's going on, as well as a theme in the lyrics - then those themes resolve when it switches to playing forwards. It's really good.

    If 1 + -1 gives us 0, then a whole note in 4/4 followed by a whole note in -4/4 should give us no sound.
    What two notes give us no sound?
    Phase reversed notes!
    So negative signatures could just be a "flip phase" indicator

    "[I figured I'd try] to start a a fight. (...) So first of all, I think Adam's answer was pretty good." You might want to work on your fight-starting skills there.
    Anyway, I definitely do think your response is a better more accurate way of having a negative time signature than Adam's. His is not "really" negative in any sense. Consider, for example, a regular 6/8 beat. You have / ˘ ˘ / ˘ ˘ with two offbeats. Which offbeat would you make the new downbeat in the chords? You have two options, ˘ / ˘ ˘ / ˘ and ˘ ˘ / ˘ ˘ /. That's not very negative-like though; -1 * -1 = 1, not some third thing. We want some sort of operation like multiplying by -1, except that you can do it three times before you cycle instead of just two, where / ˘ ˘ / ˘ ˘ leads to ˘ / ˘ ˘ / ˘ leads to ˘ ˘ / ˘ ˘ / leads back to / ˘ ˘ / ˘ ˘.
    But you know what does act like that, giving three different "states" when you multiply it? e^(120° i). That's a scary way of writing "120° around the unit circle in the complex plane" which is in turn a scary way of writing "a 120° rotation, expressed as a complex number." We get three numbers out of this rotation: 1, e^(120° i), and e^(240° i) (which replaces the 1 and -1 in the duple rhythm case); we can then multiply it by the normal positive time signatures 6/8 to get three related time signatures: 6/8, e^(120° i)*6/8, and e^(240° i)*6/8. So if we take Adam's definition of negative time signatures, then we can actually extend this idea into the complex plane in this way.
    But anyway, that tangent aside, I'm not sure if I entirely buy that definition to begin with. It doesn't really seem to map out any sort of real time, which I feel like is what the time signature is saying. And besides, why are there only two markers of accents? There are probably other characteristics of accents that can be separated out (loudness, pitch, chord changes, intensity of vibrato, and probably other weird ones we don't even think about as we perform); why don't we separate out these other aspects? Instead, directly manipulating time seems like a better way to interpret messing with that top number of the time signature. Reversing recordings is really the only way we have as universely beings to do so, so I think it's a fair way to work with that.
    Also, what happens if we mess with the bottom number of the time signature? In math, the fractions (-4)/4 and 4/(-4) are the same thing, but in music, the "numerator" and "denominator" have very different roles. Playing -4 beats, with each beat being a quarter note long, isn't necessarily the same thing as playing +4 beats, each beat being a "negative quarter note" long... depending on how we define a "negative quarter note."
    Though "messing with time" is reminiscent of special relativity (and general relativity, but that's even weirder). Reversing recordings is actually not our only way of messing with time (though it's probably our only way of reversing it); we can also travel super quickly (or near black holes, but again, let's ignore general relativity). How would we talk about a piece of music wherein one musician is on a spaceship traveling at half the speed of light relative to another, and both are moving relative to the audience? Would that change our time signature? That'd be an interesting exercise in polytonality, since the musicians both think they're playing in the same tempo and same time signature, but experience the other's playing as stretched out in time. ...Relativity is weird.
    Though come to think of it (though this is no longer about time signatures), even if the musicians are moving at a more reasonable speed, say on a train, and we're on the ground, we would hear their pitch shifting thanks to the Doppler effect. What if there's a long line of musicians on that train, each of whom suddenly drops in pitch as he/she passes us. Then the way the music sounds to an audience member depends on both what the musicians are playing and where along the tracks that particular audience member is, since the different musicians pass us at different times and therefore jump in pitch at different times. And what if every musician is on a different train? What if the train accelerates and decelerates repeatedly? In fact, the musicians could each be on a different train, and they all play the same note for the whole concert, and depend purely on the train's speed and the Doppler effect to change the pitch. That'd make for an interesting concert environment, if nothing else. (Also as a practical matter we might not hear anything other than the screeching of the train wheels.)
    ...Uh, I should probably stop thinking about this now.

    @TheSquareOnes 6 ปีที่แล้ว +7

    This method doesn't actually change the time signature though, which seems like a massive flaw for obvious reasons. A "negative time signature" should be something that expresses rhythm differently but here the rhythm is identical, all you've changed is the nature of the voice performing it. How is that functionally different from having the same line played with a trumpet or with a different synth setting? It isn't, which tells us that it's not useful as a concept.
    For what it's worth I don't think negative time signatures can be useful concepts. My version of the idea back in high school was to "start the bar" earlier by the indicated amount, if a time signature tells you the duration of a measure then a negative time signature should also tell you the duration just in the opposite direction. So if we have a passage that goes 15/16, -3/4, 7/8 the "measure of -3/4" would actually be performed starting on the 'a' of beat 1 in the measure of 15/16 in effect performing a brief polymeter. I think this is still the best answer I've heard to the question but obviously it's also completely useless since there's nothing stopping us from just writing the notes of the -3/4 in the 15/16 where they would end up anyway and ditching the superfluous notation entirely. So that's both my explanation of how it could work and also my explanation of why the concept is dumb and will probably never be useful.

    what if you played it like an extreme dynamic flip? so since like if you pluck a guitar string, the noise is mostly on the front end of the sound, you could achieve the backwards sound using a synth effect with most on the back end. then it would be practically playing backward music.

    Negative numbers are a construct that we came up with to try and explain the world around us. In reality you can't represent a negative number, you can never show a negative number of something. Negative time simply makes no sense. Kind of like negative temperatures, just a construct to help us understand our reality but there is no such thing in nature as heat only moves in one direction, just like time.
    Personally I think that it was a question that somebody asked before they thought about it and tried to come up with an answer... I too, often get these ideas where for a brief moment I feel like I'm on the verge of blowing my own mind but then I think about it and realize that I was simply either asking a stupid question or asking it in a stupid way. For me thinking about it for a couple of minutes is usually enough to get over the "mind blowing concept" and keep myself grounded.

  • @unhealthytruthseeker
    @unhealthytruthseeker 6 ปีที่แล้ว +1

    I had an idea (inspired by physics) about negative time signature, and it generalizes to complex time signatures as well. I posted this on Adam's video as well.
    I think we might be able to make sense of negative time by considering complex number time signatures (which someone mentioned in the comments). Complex numbers only make sense when you have both an amplitude and a phase, so they would only make sense with more than one time signature played at once, like a linear combination between times. In this way, a time of (1 + i)/2 and a time of (1 - i)/2 would both be 2/2 time, but they would be "out of phase" with each other. The only sensible interpretation would be that of a time-delay between the beats of one time signature and the beats of another.
    If you write the complex number as r*exp(i theta)/N, then r would be the number of beats per measure (with the Nth note getting a beat) and theta would be the offset of beat 1. So a theta of 0 would be no offset, and a non-zero theta would be offset by N*theta/(2*Pi) beats. Thus, if you had 2/2 and 2*exp(i Pi/2)/2 = 2i/2, the first beat of the second time signature would be played 2*Pi/2*1/(2 Pi) = 1/2 beat later than the first beat of 2/2.
    From this, we see that a positive imaginary signature gets a quarter-measure delay, so a negative time signature would simply represent a half-measure delay relative to a positive time signature. Note, this only makes sense when played against another time signature. -4/4 against 4/4 would be played 2 beats later than 4/4.
