Metronome Synchronization

[DexlessJoo]

you must have been so high

[jokurulez]

better than orgasm

[Arexsis]

I've noticed this with our car's left turn signal and the car ahead's left turn signal, it'll be in synch then drop out and back in again.

[iBeCruciaL]

What!!! I've been watching porn all my life when this was here OMG!!! what a wasted life... :(

[jlebesis]

44 drummers disliked this very in-time youtube video...

[drewbloo99]

this gets me off-beat. ;c

[G3kDxScOpEzz]

i didnt need to know all the other stuff just say they are set at differnt beats

[tparker37]

oh, coupled systems of differential equations! you got me again!

[RUOCCOLOCO]

dont you have to play practice...?

[kbyer]

Madness!

[odiousominious]

one would pass the other in degree eventually

because its faster right

if it were the same speed it wouldn't change lol

still, how does there base change the outcome

does one move the base enough for the other to be changed by the base

[mistahmeaner]

1. Pause at 0:00 2. Hold down and left arrow at same time. 3. Press and hold up. 4. Enjoy your game of Snakes

[olmstead25]

i never thought my life would come to the point of watching metronome's on youtube..... ~~hangs head in shame~~

[CowboyFromHell092]

sword fight

[meenkmeenk]

I was hoping the cans were gonna do something cool with keeping time too - teardrop

[cursedswordsman]

Oh, cool!

[748334]

Oh I get what is going on. The faster one is making the board and cans move making the slower one move at the same pace!

[petujaymz]

I want a metronome for no reason

faggots

[felipedjg]

Thats cool.

[MEGABAM1999]

they go for ever but the noise is addictive

i was about to cancle than i started to listen

the sound is cool

mmmmmmmmmmmmm

im gonna watch it again

[mejico94]

i love physics

[Apple666maya]

woooooow !!!! hails physics !!!! I love music and the use of metronome was always a pain in the ass!!! but this is awesome  science and music!!!

[jimipage6662]

( o.°) Blown mind!!!

[icemanbx]

Huh? what is so special about this? The metronomes will be in sync at one point because of the difference in frequency.

What kind of significance does the moving base make?

[canucmesucker]

@icemanbx the fact that they move shows that momentum is unequal, but when they are equal, the base remains still.

[MaximPodolsky]

@icemanbx They will be in sync not "at one point", but at all times, after a certain time. What you're talking about is beats produced by two oscillators running at slightly different frequencies that are periodically in and out of sync. In this case, however, they will actually syncronize, i.e. the final frequency of both is one and the same.

[vladeckkk]

@MaximPodolsky

if he removes that piece of wood from the cans the metronomes will desynchronize because they are set at different frequencies

[MaximPodolsky]

@vladeckkk Well yes, you can't change the length of the pendulum by putting it on two soda cans :) I think a similar effect can take place when helicopters fly in formation, their rotor blades become syncronised. Though I am not sure if that's just a myth. I read it in a book written by a military pilot.

[sporks102]

this is some trippy stuff!!!

[parkourmormon]

Close your eyes and enjoy the ninja-fast ping pong.

[youboli]

@parkourmormon

Fuckin great match

[skintigh]

I was told as a child that two grandfather clocks in the same room would eventually synchronize their pendulums and I never understood why. Now I do.

[rg0057]

@skintigh , the reason the metronomes work is because they are transmitting forces to each other via the mobile platform they are on, giving each other a slight kick needed each time in order to stay in sync. I would not expect grandfather clocks on a fixed floor to work like this, because the floor won't be moving, and can't deliver that kick.

[skintigh]

@rg0057 Seems they can and do. YouTube crashes whenever I post a link, so go to wikipedia and search for "Odd sympathy"

[Neko3031]

I liked the part where it ticked.

[CultOfKingsTV]

reminds me of dec. 21 2012...

[The202Maniac]

Yeeeeeah ! AAAAMAZING !!! ... no seriously you physic lovers are crazy !

[DanteLouhv]

Dude. That's fuckin amazing.

Although, now I'm finally in a Physics class, it makes sense and takes the magic out of it... BUT STILL!

[Ninjafruit123]

I want a Coke.

[se7en98]

that was intense

[andymillerisdabest]

I liked the bit where the metronomes went tick tick tick tick tick tick tick tick tick tick tick tick tick tick tick tick tick tick tick tick tick tick tick tick tick tick tick tick tick tick tick tick tick tick tick tick tick tick tick tick tick tick tick tick tick tick tick tick tick tick. Not a tock in sight,

[WiredCabose7732]

the clicking is nice

[rico010589]

GOOD ISH U SHOULD CHECK ------physocological word play with no metronome"""

[conleycd]

It's actually kinda neat. - I think The experiment shows that 2 physical sources operating at slightly different times and out of phase with each (complete opposite) to start - will eventually regulate to the same movements (in phase - i.e. going the same way, and in time [sync]) if they are both supported on the same base (the cans on the board).  You can watch how the one changes phase and then eventually both sync up exactly. Kinda neat.

[jrabzkie]

 i dont understand it one bit but i like the video. 5/5

[MarilynMansonsVagina]

you sound like strongsad

[THEn00b557]

Cool!

[mayorde18]

i didn't understand the experiment... but how come the two metronomes get to the same bpm....?? that part is weird :O (i'm musician and use metronomes a lot)

[216trixie]

@mayorde18 Answer is "entrainment".

[Russenka]

nice beat

[Psychostick1]

Looks like 2 robots wiping the floor ,lol

[screamolives]

@Psychostick1 Fucking weirdo. lol

[DesignRec]

@Psychostick1 haha yeah it does!! :) :) :)

[idrumchick]

@Psychostick1

That was a friggin funny response

[fibonacci227]

WHOAAAA

[marvi182]

WOooooooW i've watched all the video !! hypnotk 5/5 stars

[188metalhead881]

what's that? a crazy tempo game? #LOL

[RhianaM]

i hate when windsheild wipers do that.

[yoenvideo]

Is this what geeks do to kill their time?

[NiceButNic]

THEY ARE GOING TO TAKE OVER THE WORLD

[WildMaverick1200]

where did you get those funky little metronomes?

[bighorsett707]

0:53 dont you just love up beats

[ballbagbaggins]

this video is better in my opinion watch?v=QkXHwRf15Ts

[ballbagbaggins]

they clearly are not in time with each other or is something else supposed to be happening here?

[MustNotRead]

wtf....they're like, intelligent beings or something. freaky

[cattkiller]

thumbs upp

[Generationxxxxxxx]

thats pretty sick

[pyrioni]

Wow! cool

[maxbigazzi]

Wow!!

[Reminiscable]

Wait... It was fun for a while, and then... They Stay In Phase?!!! Whoaaaa.

[RODALCO2007]

Excellent video, I am surprised that the interaction between metronomes is so fast.

I have managed to synchronise 3 pendulums electrically of 3 Bürk master clocks, via a 30 second impulse from a Gents master clock.

[ogdroadsong]

Wow, I just came in my pants!

[hangover71]

were any animals injured during this..?

[eatthepoor000]

it's the coke. Unsicronized liquids.

[rollingklouds]

Husband and wife inside the house and outside.

[guiliano4]

bizarre

[fluteler]

Suppose they were on the floor. They would go into phase, out, and in again. They would not lock.

Coupled by a movable base, they transfer enough energy to one another to overcome the pre-set mechanical frequency.

Compare this to adjacent strings on a piano. Do they pull each other into pitch? Do wind instruments pull each other into pitch?

If digital oscillators can be made sensitive to pitches already playing, can one get the same tightness on a tempered keyboard that a garage band gets?

[swiv2d]

so basically the wooden base is what's converted the change in momentum, you'll have to forgive me it's been while since school what is the equation for that

[mcphaila]

It's not a problem with the metronomes, it's just the way the world works. They start anti-phase, and end up in-phase. There are no other stable alternatives so 2 pendulums set closely together, with similar BPMs will always end in-phase. It works with people too... creepy isn't it?

[raunchbear]

Cool, I'd like to see the equations for this

[TinkersSinyo]

lol

[drkev]

If only I could get real musicians to do that!

[Konichiwa55364]

is there a point to this?....congratulations on having alot of time on your hands and actually video taping it to post on youtube.

[scubaguy30]

hypnotic

[Touristo07]

Does It ever end? D:

[alyssacroacia]

That's wicked

[rIndiaan]

the metronome is like a tiny drummer used to keep the beat when your making music solo :P

[ijewa]

KLACK KLACK KLACK KLACK KLACK KLACK KLACK KLACK KLACK KLACK KLACK KLACK KLACK KLACK KLACK KLACK KLACK KLACK KLACK KLACK

(It's cool that in the end, they synchronize; in a perfect world, that wouldn't happen)

[Blackinferno15]

dude in simples terms your mets r a peice of fucking shit!!!

[alexfanx]

That's not the point.

[Blackinferno15]

they shouldint sink in dude if if there set on differnt tempos n then all of a sudden the sync um theres an issue there

[alexfanx]

Read the description.

[jameseverett100]

BATMAAAN NANANANANA BATMAN!!!!!!

[ginabobinafofina]

HA! when they first started clicking I started singing "Single Ladies". lol

[WasteTimeKillingCats]

Rofl me too. :P

[zakcopelandmusic88]

trying to write a lead, so i wanted a metraome, stumble upon this and now ive a headache, thank you for the inconvinence

[RecksRead]

There could be corrupt flaws in the weight or the springs causing a fluctuation of consistency. No?? These are not perfect chronometers by any means. They are wind up toys essentially. One could be wound more than the other. Just some observations.

[joshhoe]

hold on.

if you put two metronomes side by side, and one is going at a slightly lower rate than the other, obviously the faster metronome will "catch up" with the slower one after a while as the difference in timing accumulates. Then the two metronomes will appear in sync. After awhile, the faster one will go out of phase again. This is exactly what is happening in the video!

You don't need any physics experiment or even a common base at all!

[becomepostal]

After awhile, the coupling produces a permanent phase. They will wot "phase out after awhile". This can be mathematically proven with linear algebra, and this is what this experiment shows at the end. Of course, it would take an "infinite amount of time" to be *really* proven without the math. LOL.

[mdeyab]

this will not happen if there is no common base ... notice the two metronomes started in the opposite direction but at the end they are moving on the same direction with the same frequency.

[bucketheadhero]

joshhoe, you dont know what your talking about.

How come then by 1:25, the two metronomes are in sync for the remainder of film?

Your argument would predict them going out of phase again within 30-or-so seconds left of film.

Please explain

[Dooohicky]

i'm really not sure whats going on here, but i like the clicking noise XD

[ArkAngelSlave]

lmao; I am with you. I just wanted to know what a fucking Metronome was because it is soppose to help with Guitar...lmao; The clicking is awesome XD

[soildsnakefoxhound]

@Dooohicky its called metronome it is to help psychics clear there mind and enter the alpha state of the paranormal word try relaxing with only 7 mind functions working and it may happen

[pinup60]

@Dooohicky hahahaha me too

[AlphaKennyl]

@Dooohicky its suspose to help u with beats...like example with a drum set helping u stay on beat without slowing down/or going faster.

[thebeatboxbbca]

genial !

[kylej88]

annnnnd if he put only one on there... it wouldnt change much, that was dumb

[defdeezy]

it'd be completely different. you have a shit ear, apparently.

[kylej88]

im talkin about the supposed "Momentum" defdeezy.. apparently you dont know what the fuckin experiment is im not talkin about the sound.

[defdeezy]

apparently i don't know what the experiment is, i WAS talking about the sound. so, uh, yeah.

[kylej88]

so uh yeah what the hell do you think everyone else is talking about haha

[fordboy111591]

wat was the point in this

[SmileyFace131213]

cant you hear it? they are pretty much in sync at first,but then they arent,then they are,and it's really cool!!

[fordboy111591]

i think its kinda dumb wat does it prove nothing important

[SmileyFace131213]

your right,it doesent prove anything important, its just a kinda cool little thing lol

[hattoriheiji11]

x3

kewl~~!!

[tbommerrulez]

if the second one is set at a lower rate, eventually one will break or reset when they are turned off

[MichaelRecycles]

that didnt need to be 2 minutes long ;/

[aDorkyman]

Is the proper term "conservation of momentum" here, or is something simpler happening? How about one metronome physically moving the other metronome such that the escapement trigger point is reached sooner (or later) than initially programmed, and that the net effect is a sort of negative feedback loop that eventually syncs the two devices?

[Jer1400]

Yeah, probably something simpler like that stuff you said. :D lol

[konkov123]

@aDorkyman consvervation of momentum is grade 11 high school stuff, "escapement trigger point and negative feedback loop" those are simpler terms? Are you fucking drunk? Your trying to make it more complex whilst not making sense at the same time.

[talkboxmayhem]

Are there any other equilibrium points for this? It seems that the synchronized equilibrium is asymptotically stable - perhaps there is an unstable one - like their initial condition?

[16mmDJ]

fascinating!

[tiemahshoo]

what beat do they sync into?

[clandestine0724]

About 191 bpm

[PRWNSillyMoose]

better than u

[moncheej1974]

So Cool!

One E and A two E and A three E and A four E and A....

[SuperRider74]

ive always been told im wrong when i say "1-e-and-a" and i was told the correct was was "1-e-AN-a"

i dont think it matters though

[townsend127]

I would imagine that it is '1-e-and-a' since you count "1 and 2 and three and four," not "1 an 2 an 3 an 4."

Either way it doesn't really matter.

[toasted2009]

I don't get it... But want to learn!!!

[MajorFenix]

Basically, the one on the right is slower and by making a base that can move, they eventually balances the swaying and sychronize... Well at least for a little while...

[yoohdee]

That's impressive. Read some comments and apparenlty people don't understand physics. Noobs. Btw, good job

[MilkshakePlease]

What kind of metronome is that? Where can I find it?

[ogfeen]

what is the point of the coke cans?

[Pheauxr20]

Just goes to show that men can F with their own contraptions. :)

[lbigbadbob]

Steve Reich eat your heart out.

[ogfeen]

what the fuck is so special about this?

[ALEE775]

its called knowledge.

[drummerboi8]

a example of everyday stuff like this is when you have your turning signals on and so does another car in front of you haha

[uploadJ]

Can you 'splain the coupling between the two turn signals (how they couple)?

[drummerboi8]

exact same thing as this

[uploadJ]

drummerboi8: "exact same thing as this"

Huh?

That doesn't answer the question how blinkers on two different CARS blink together .. unless you somehow mean they blink telepathicly maybe ...

.

[jaxm666]

the idiot thinks that just because two car turn signals will eventually blink at the same time due to an overlap of frequency pulses that it's an example of synchronization...

[richtomes]

Brilliant piece - I especially love the genius rhythmic invention, and the implicit melody, not to mention the moral - bravo the composer, you are a credit to the great classical music tradition.

[ecchy]

this isn't really physics, no!?

these metronomes must be a little cheap, being unable to keep their own pace when external forces plays on them...

[nulldream]

you don't get it do you, read what the description says.

[ecchy]

were you talking to me?

I understand the physics of the thing, that's not the point. What I say it that a metronome should keep his pace. You expect a GOOD metronome to keep the beat, not to be influenced by the environment.

So I was not questionning the physic principle... but the quality of the metronomes.

[srvonderfecht]

ecchy, bad metronomes good metronomes, doesn't matter. Put them on a freely moving board and the same thing will happen: synchronization. Pretty cool, huh? Check out the Millenium Bridge, it kinda did the same thing except with people instead of metronomes.

[guacanagari]

????? wow

[kakashi76767]

HEY EVERYONE! THE METRONOMES ARE SELF-AWARE!! stupid. lets see how they would deal with wind blowing one way or another.

[the5445]

i love physics, and this confused me lol

[panefuldeath]

did u come up with this yourself? this is really cool.

[david7992]

nice... i suppose

[foshizle07]

as boring as it was, it was really interesting

[Lonnie1699]

where do you get metronome?

[crazyfreak1919]

music store

[gig603]

cool

[lisarisa18]

Flobot does not need one to keep rhythm.

[serbin16m]

ahahahahah

[GzForumPoly]

hahha they can ride a bicycle without handlebars, too.

[Layk35]

lolz that song is the only reason i went looking for metronome vids

[tanner123driver3]

i need a metronome fro my drums

[redd001]

Ok? Interesting, just looking for online metronome and this came up? ...ok xD

[wiimaster494]

i play drums and im googling

[00J4KE00]

lol i was just looking for tht free online metranome then this came up

[PenguinIce12]

Me too!!! I play violin so I was searching for a free online metronome on google too!

[Shadeslayer527]

Lol me too. This is rly interesting anyway

[chansherly212]

hahaha me too!

[glueman89]

hahaha 126, 567 views on this???? boring...

[iToLdUs00]

to many big word he just used..i can't belived i even watched this video....NERDY

[gold019]

i wish i was that smart.

[Despotailustrado]

holy shit what happens!

i still can't understand

could someone explain please?

[metrobot1]

cool. because the base is not fixed the 2 metronomes (set out of phase) eventualy beat in phase whith each other?

[Lesley9999]

odd...............

[webfxca]

Wow!

[Jetboy1993]

NERRRRRRRRDS

[MelaniePortrip]

Yeah, I'm sure you wish you were smart.

[Jetboy1993]

Who are you, some geek twat. Piss off

[MelaniePortrip]

Who are you, some idiotic moron? Yes, yes you are. Now go fuck yourself.
