This is AMAZING! I am using this with my 8th grade science class today to introduce their planetary music project. Each planet has a different diameter with will be used to determine a starting pitch. Each planet's orbital velocity will be used to calculate a tempo and groups will use each of these starting points to create their own collective musical composition. Of course, the pitch and tempo must be to scale with the actual astronomical measurements. Thanks for the inspiration!
Could you make like a 10 hours version of the end of the vidéo ? :-) I'm just fascinated by this ! It's so awesome ! And only last less than 1 minute :-)
Wow... you can hear the pattern, its not just random blips... I just imagine the formation of the system where amongst the chaos this resonance starts to pronounce and then you get what you have here today.
Yes! They were tuned into this stable pattern one at a time by slow orbital migration, similar to how a band tunes up, although they've lost a bit of the fine tuning over the last few billion years.
The migration is caused by the planets interacting with the gas disk they formed within (this is the same thing that brings some giant planets right up to their stars, "hot Jupiter's"). It seems that TRAPPIST-1's disk was calm enough to allow the planets to move and then get stuck in this stable resonant chain, which wouldn't be possible in a more turbulent disk. The later detuning was caused by tidal forces between the planets!
Ah... so its this slight shifting movement that allows the planets to fall into a resonance. Is the tidal forces due to their rotational differences? Perhaps one or more not tidally locked? I can't imagine the resonance just naturally being unstable unless it wasn't the most stable resonance they can achieve?
Like Matt said, their varying interactions with the surrounding disk from which they formed cause them to drift into stable resonant configurations. They are subsequently detuned by the star raising tides on each of the planets, like our Moon does to Earth. Because the planets are on elliptical orbits and therefore periodically get closer and farther from the star, the strength of the tides changes, and they're effectively squeezed and decompressed repeatedly. Like if they were tennis balls, this causes them to heat up. For technical reasons, this dissipation of heat in the planets causes them to detune away from exact resonance.
Ah.. I think I appreciate it a bit more on the second listen.. "we simply scaled up the orbital frequencies by 212 million times" well.. that explains a few things :)
This is Powerful , it feels like the music is expanding my mind to OPEN a GATEWAY to another DIMENSION, ???.. Does anybody else feel this?? please comment below?!!:)
Doood I love this I want to make my own with Ableton. Did you follow a set up based on 16th scale or something? Do you have a link to a good place to translate the music notes in Ableton or just gotta do it one by one?
Thanks! We wrote a python code to make the midi file with the closest notes and then fine-tuned them in Logic to match the relative orbital frequencies. You can find a link to the code and the midi file at system-sounds.com/trappist-sounds
What's the margin of error on the orbital period measurements? These ratios are considerably worse than equal temperament. With a factor of ~ 200 million in there presumably there is some leeway...
The period ratios are known very precisely but they have drifted away from being exact whole number ratios since their formation (mainly due to tidal forces). For example the ratio of TRAPPIST-1h's period to that of TRAPPIST-1g is about 1.52, instead of 1.5 which is why the notes are slightly out of tune. They were much closer to equal temperament shortly after their formation. Read system-sounds.com for more info on the scaling, it was exact but is irrelevant for the relative tuning. Thanks for watching!
Due to the planet-planet gravitational interactions, the instantaneous orbital periods of the planets vary, and so the pitch of each note should be slightly different during each transit (by about 0.2%). I don't think this slight variation is perceptible through beat frequencies, but it might be fun to try out!
Great idea! This is the same principle behind the transit timing variations which were used to estimate the planet's masses. A 0.2% difference changes the notes by about 1200*log2(1.002) = 3.45 cents (percentage of a semi-tone) which is below the threshold for human perception of a single note (~5-6 cents) but as you point out, when played together would produce a beat frequency of a few seconds. Cool, we'll give it a shot in a future project!
This is a great idea. It's important to note that our perception of tuning differences is magnified tremendously when it involves the interaction of complex tones (most of the perception research is done on sine waves)
Fodaaaaaa. Que massa as orbitas são tão sincronizadas que cada órbita e uma nota musical perfeita bela sinfonia da natureza,esse sistema planetário e o meu favorito.
It was definitely not the best sounding music, and honestly I feel like the article - which I read first - kind of overexaggerated how good it sounded, but I will admit it doesn’t sound terrible. It sounded a little bit random at the beginning but there’s definitely a pattern to it and I think it sounded cool at the end. Not gonna be listening to this on repeat by any means but it’s still quite interesting. I’d also like to hear what that other solar system that they tried it with sounded, because it supposedly sounded random and not good at all, so the comparison would be nice. For a solar system, it’s pretty good I think that the thing that I don’t like about it is at 0:13, the second planetary note is offset a little bit, and then later the other planets are offset when they join in
This is just music, I want an actual song with lyrics about the Trappist 1 system. Are we so selfish that we only make songs about our own solar System? And 125th comment.
Two things. First - don't make a fool of yourself by complaining that the piano is out of tune. The tuning is an expression of the time that it takes planets to rotate relative to each other. The fact that they sound intelligibly in tune at all is the interesting thing - in other words that the orbits of the different planets are ALMOST synchronised in simple patterns/relationships. To some degree, it's not that big a deal - I would not be surprised if there were plenty of naturally occurring phenomena from which similar sets of ratios could be drawn and then expressed as the pitch of notes....crystals, cellular division, atomic elemental organisation spring to mind. maybe the famous proportions of shells. You could if you liked, aurally express these ratios as timbre or volume, with the same degree of arbitrariness or validity. What makes this example somewhat compelling to me is that the rhythm (ie. the triggering of the notes) feels like (and is) a much more direct expression of the orbits - we can look at the planets whizzing round and imagine a physical 'clapper' or something that actually produces the note at the given (somewhat arbitrary?) point. Musical movement as a direct 'result' of the planets' physical movement. Second - To the creators - have I misunderstood? The acceleration of the drums-resulting-from-conjunctions is a human artistic artefact no? Of course, the gradual addition of more planets is, both times? Anyway - fun!
I think the whole point of this is that this particular system is so naturally resonant that the frequencies of the orbits are THIS close to harmonising perfectly... just a tiny bit off. If they'd tuned it then the only thing the music inherits from the system is the timings, which isn't why they did it.
That's exactly right :) That's one of the things that sets TRAPPIST-1 apart from every other system we've found. With many new surveys planned to search for planets around cool dwarf stars, the hope is that more of them will host systems in resonant chains. It may be that low mass stars have calmer planet-forming disks, which would let more planets to get stuck in resonance.

If I was in the planetary neighborhood I'd file a complaint for all that noise.
That's a common misconception.

You should hear what Sol (Our solar system) sounds like
@@Canadian_Zac Plutos a bit respectful, though. I thank him sometimes.
it goes from classic music all the way up to heavy metal.
thats not even heavy metal. tf are you talking about.
The last 30 or so seconds sound really cool. Now I'm wondering what our solar system sounds like.
Absolute chaos
@@Canadian_Zac yep there is your answer
I like how it feels off tempo first but the more sounds you add it makes more sense.

Woah! So is that the bases of orbital migration or just the result of it. Or both?

Amazing! Thank you.
I'd love to hear that about our solar system

would it be possible to convert the ratios of planetary arcs of aphelion and perihelion into music?
Terry Riley is probably one of them. ;)

It would have been a lot less irritating to the ear if you adjusted your tuning algorithm. It comes off sounding like an out-of-tune beer hall piano.
I think the whole point of this is that this particular system is so naturally resonant that the frequencies of the orbits are THIS close to harmonising perfectly... just a tiny bit off.
