Exoplanetary Interv (Disquiet Junto Project 0272)

my wife says that it was better last night when it was free form improvising. now it´s stuck in the pattern, unnerving valse. she is a tough critic.

If I’m correct, the planets were discovered by a Belgian(that’s why the Trappist name)…
I started with getting a midi-file from P22(text to music) from every Belgian Trappist. I’m not gonna name them all, but I can tell you there all excellent beers!
I put different guitar sounds on all 6 of them and then followed the orbits(24, 15, 9, 6, 4, 3) from Mzero’s webpage.
When I finished the song, I realized that… I am never gonna work for NASA!

Suss Müsik is fascinated whenever a new planetary system is discovered. We imagine the excitement must be similar to a child finding loose change while building sand castles, albeit at a much grander cosmic scale. It’s evidence that life could have existed before we entered the scene, giving resonance to our actions.

According to an article on Gizmodo, a new Harvard University study raises the compelling evidence that the TRAPPIST-1 planets are close enough to each other that microbes could hop from one planet to another, skipping over rocks suspended in space between forms. Some scientists even suggest that life on Earth could have started this way, but don’t tell your Sunday School teacher that.

For this short piece, Suss Müsik created a series of simple polyrhythms on piano: 3:2, 4:3, 5:3 and what we think is sort of close to 8:5 (we lost count). These phrases were cycled “in orbit,” giving the effect of emerging and receding into listening distance. Individual notes were then allowed to “travel” from one phrase to another within a four-octave range.

The piece is titled Panspermia, named after the theory that life on our planet originated from chemical microorganisms who traveled through outer space searching for an environment suitable for habitat. The image is a chunk of marble pilfered from the cliffs of Carrara, Italy.


We considered this idea as well. Yours is much, much better than ours would have turned out.

Nicely done. This week’s theme almost needs two weeks to execute an idea properly. Yours sounds very resolved.


Your contributions are always amazing.


As mentioned in my comment: your piano phases are much more musical. You didn’t need to bury the poly-rhythms in space-sounds, filters and ambient synths. Mine were really too crazy. :wink:
I did the maths right but your piece shines musically. Bravo.

This isn’t exactly the “assignment” but it has to do with the intervallic relationships of the planets. A few months back I built a sonic orrery with the JavaScript web audio api to express Thomas Kepler’s Harmonices Mundi or Music of the Spheres. It is build upon historical calculations and his understand of orbital velocity. You can listen to it here: https://jeffreypierce.net/kepler/ (it works best in Chrome)


You are most kind. Thank you!

Just listened to all the submissions so far. Wow, you people really hit it out of the park! I was mildly worried while developing this, that the implied tonality, being not all that exoitc, would result in an underlying uniformity to the pieces. HA! No need to have worried there, so many ways to express one set of planets!

@fjna - I’m going to sit this one out! Even though it is so up my alley, I’m a little too close to it after all the work on developing it.


Thanks! I didn’t have much time to work on it because of other commitments, so I had to resolve it quickly!

As well at the really cool phasing, I love the use of dynamics in the piece. Excellent!

Cheers Juntonians,
This weeks music and video! This was fun :smiley:https://soundcloud.com/user-651760074/sisters-of-trappistdisquiet0272
Music-There is always something about space discovery and exploration that gives me a sense of hope and promise. And honestly, after last week, I needed a more uplifting prompt. I wasn’t sure where to start so I began building a rhythm with suitably space like elements. I built a kit in Patterning and set it to a lively 120 bpm. I was able to get a nice polyrhythm using the orbiting ratios and then went in search of patches. Originally thought EDM style but settled on a less frantic sound that seemed promising with nice movement. The synths used were Sunrizer and Waldorf, while the piano and all mixing are in Cubasis with some eq, panning and Zero Reverb for the piano.

Video - Everything you see in this video I created in Photoshop and imported to iMovie for final editing and render.




i think i drifted off target on this one a bit… but it was fun!



Polyrhythmic exojam! I wrote this very simple tidal program, picked some samples, fade in the different ‘planets’ one by one, then jam/riff around by ear with a pattern inside the square brackets for each planet, build up a little jam then fade out. Teensiest bit of reverb added to the recording before uploading to soundcloud.

Alright, I’ve settled on a result after a few attempts.

My idea was to loop notes from various parts in the scale suggested by the Trappist orbits, starting from the low B on a five-string bass guitar.

They seemed a good collection of notes. After exploring them with MIDI instruments I recorded a long take noodling through them on the bass guitar.

After exporting one draft, I decided I could get a better result if I went back to the original idea. So I picked six different parts to loop then, after arranging them, extended the sections where I’d played the looped notes to include longer takes.

Then they were panned across the stereo channels and reverb and delay added to give them each more character and depth in the mix. There’s a bit more reflection and the earlier version on my blog.


UPDATE: I’ve just received this e-mail from the lead astronmer, Michaël Gillon, of the TRAPPIST-1 discovery team. I wrote him to let him know of this project, and this page. He replied:

Thx a lot, that’s amazing! I’m now in the Atacama desert commissioning the first SPECULOOS telescope, and listening to these nice music compositions while watching the stars is just an awesome experience!


But wait, there’s more:

PS: I suggest you to have a look at this paper: https://arxiv.org/abs/1703.04166 :wink:

So, I dig into that paper - published just 6 days ago - and find what he’s hinting at: They’ve narrowed down the orbital period of the seventh planet, h, and: it’s resonant, too!

It’s an octave below planet f, so F₁ in the scale I gave. And like the pattern, this one is flat from the just or equal temperment note by ~44 cents - so double the “off” of note above, and shy of half a semitone. But, at 42 Hz, it’ll be like a deep tone on a pipe organ!

Yes, my web page has been updated!

That is stupendous — both his correspondence, and the 7th planet!
