Disquiet Junto Project 0272: Exoplanetary Intervals

The Assignment: Use music to express the relationships between planets.


Each Thursday in the Disquiet Junto group, a new compositional challenge is set before the group’s members, who then have just over four days to upload a track in response to the assignment. Membership in the Junto is open: just join and participate. A SoundCloud account is helpful but not required. There’s no pressure to do every project. It’s weekly so that you know it’s there, every Thursday through Monday, when you have the time.

Tracks will be added to this playlist for the duration of the project:

This project’s deadline is 11:59pm wherever you are on Monday, March 20, 2017. This project was posted in the morning, California time, on Thursday, March 16, 2017.

These are the instructions that went out to the group’s email list (at tinyletter.com/disquiet-junto):

Disquiet Junto Project 0272: Exoplanetary Intervals
The Assignment: Use music to express the relationships between planets.

Recently, scientists announced the discovery of a nearby star system, TRAPPIST-1. Orbiting its ultra-cool dwarf star are seven planets, three in the habitable zone. Remarkably, six of the planets form the longest known chain where each orbits at a resonant frequency of it’s neighbor. From the slowest, the planets orbit at: 1x, 4/3x 2x, 3x, 5x, 8x. If you think of those as vibrating strings, they form a chord or scale: the slowest planet is the root, then fourth, octave, octave and fifth, two octaves and major third, three octaves. Major thanks to Junto participant Mark Lentczner for having taken the lead in proposing and developing this project.

Step 1: You’re going to record a composition employing these ratios, as a scale or chord — or a polyrhythm for that matter — as a means to express a sense of these newly discovered planets. Keep this in mind.

Step 2: Consider those intervals, play with them a bit, and think about how they can be employed to represent independent yet interdependent bodies in motion.

Step 3: Review the information on the relative orbits of the TRAPPIST-1 planets here:

http://www.ozonehouse.com/mark/dj/trappist.html

Step 4: Create an original musical composition that explores the exoplanets’ relationships based on Steps 1, 2, and 3.

Five More Important Steps When Your Track Is Done:

Step 1: If you hosting platform allows for tags, be sure to include the project tag “disquiet0272″ (no spaces) in the name of your track. If you’re posting on SoundCloud in particular, this is essential to my locating the tracks and creating a playlist of them.

Step 2: Upload your track. It is helpful but not essential that you use SoundCloud to host your track.

Step 3: In the following discussion thread at llllllll.co please consider posting your track:

http://llllllll.co/t/exoplanetary-interv-disquiet-junto-project-0272/

Step 4: Annotate your track with a brief explanation of your approach and process.

Step 5: Then listen to and comment on tracks uploaded by your fellow Disquiet Junto participants.

Deadline: This project’s deadline is 11:59pm wherever you are on Monday, March 20, 2017. This project was posted in the morning, California time, on Thursday, March 16, 2017.

Length: The length of the finished piece is up to you. Three to five minutes feels about right.

Title/Tag: When posting your track, please include “disquiet0272″ in the title of the track, and where applicable (on SoundCloud, for example) as a tag.

Upload: When participating in this project, post one finished track with the project tag, and be sure to include a description of your process in planning, composing, and recording it. This description is an essential element of the communicative process inherent in the Disquiet Junto. Photos, video, and lists of equipment are always appreciated.

Download: It is preferable that your track is set as downloadable, and that it allows for attributed remixing (i.e., a Creative Commons license permitting non-commercial sharing with attribution).

Disquiet Junto Project 0264: Time Travel

Record a piece of music that plays with the perception of time.

Membership in the Junto is open: just join and participate. A SoundCloud account is helpful but not required. There’s no pressure to do every project.

These are the instructions that went out to the group’s email list (at tinyletter.com/disquiet-junto):

Disquiet Junto Project 0264: Time Travel
Record a piece of music that plays with the perception of time.

Step 1: Recorded music is, generally speaking, a fixed object. It’s a document. It proceeds linearly, over time. It is, in the terminology of fine art, “time-based.” That said, music has the power to change one’s perception of time. Slowing and speeding tempo alone can alter a listener’s understanding of what is happening. Backward masking, sublimated hints of themes yet to come, the sound of a tape in fast forward mode — those are just a few ways that a composer can suggest that time is not moving linearly. Now, consider for a moment the tools available to give an impression of time doing things other than proceeding in a steady forward motion.

Step 2: Record a short piece of music that takes time travel as its theme, using ideas that resulted from the consideration in Step 1.

Five More Important Steps When Your Track Is Done:

Step 1: If you hosting platform allows for tags, be sure to include the project tag “disquiet0264″ (no spaces) in the name of your track. If you’re posting on SoundCloud in particular, this is essential to my locating the tracks and creating a playlist of them.

Step 2: Upload your track. It is helpful but not essential that you use SoundCloud to host your track.

Disquiet Junto Project 0248: Galactic Tick

Celebrate the new celestial holiday in music.

Each Thursday in the Disquiet Junto group, a new compositional challenge is set before the group’s members, who then have just over four days to upload a track in response to the assignment. Membership in the Junto is open: just join and participate. A SoundCloud account is helpful but not required. There’s no pressure to do every project. It’s weekly so that you know it’s there, every Thursday through Monday, when you have the time.

Tracks will be added to this playlist for the duration of the project:

This project was posted in the afternoon, California time, on Thursday, September 29, 2016, with a deadline of 11:59pm wherever you are on Monday, October 3, 2016.

These are the instructions that went out to the group’s email list (at tinyletter.com/disquiet-junto):

Disquiet Junto Project 0248: Galactic Tick
Celebrate the new celestial holiday in music.

Project Steps:

Step 1: Read up on the Galactic Tick, a new proposed holiday exploring, as described by Popular Mechanics, “how people’s perceptions would change if they really realized the one fixed point in their celestial understanding, the mighty sun, was also in flux.”

http://www.popularmechanics.com/space/deep-space/news/a22492/galactic-tick-day-september-29/

http://galactictick.com/

Step 2: Devise a short piece of music in celebration of the Galactic Tick. Perhaps you’ll explore the distance of 225 million years, which is how often the Earth fully circles the center of the Milky Way. Perhaps you’ll find cosmic meaning in 1/129,600,000, which is the “centi-arcsecond” employed by the Galactic Tick planners to make the period of time more human-comprehensible. Perhaps you’ll find meaning in 633.7, which is the number of days between celebrations of the Galactic Tick here on Earth, or 1.74, which is the number of years.

Five More Important Steps When Your Track Is Done:

Step 1: Per the instructions below, be sure to include the project tag “disquiet0248” (no spaces) in the name of your track. If you’re posting on SoundCloud in particular, this is essential to my locating the tracks and creating a playlist of them.

Step 2: Upload your track. It is helpful but not essential that you use SoundCloud to host your track.

Step 3: In the following discussion thread at llllllll.co please consider posting your track. (Assuming you post it on SoundCloud, a search for the tag will help me construct the playlist.)

http://llllllll.co/t/music-for-the-galactic-tick-disquiet-junto-project-0248/4744

Step 4: Annotate your track with a brief explanation of your approach and process.

Step 5: Then listen to and comment on tracks uploaded by your fellow Disquiet Junto participants.

Deadline: This project was posted in the afternoon, California time, on Thursday, September 29, 2016, with a deadline of 11:59pm wherever you are on Monday, October 3, 2016.

Length: The length is up to you. One minute and 44 seconds seems like a good length (that’s roughly 1.74 minutes).

Title/Tag: When posting your track, please include “disquiet0248” in the title of the track, and where applicable (on SoundCloud, for example) as a tag.

Upload: When participating in this project, post one finished track with the project tag, and be sure to include a description of your process in planning, composing, and recording it.

Stellar Catalogue Sonification

From the ancient Greek astronomer Hipparchus to the ESA's Hipparcos satellite

Musician and computer science PhD candidate Jamie Ferguson teamed with the European Space Agency to develop a unique sonification of early and contemporary maps of our sky. As described at the ESA’s website, “The improvement in the quantity and precision of data, as well as the increased information content and dimensions contained in each catalogue, are palpable as the sound clip evolves from the ancient Hipparchus to the modern Hipparcos.” Hipparchus is the ancient Greek astronomer, while Hipparcos is the name of the ESA satellite. The post goes into great detail about how each of the “stellar catalogues” was translated into sound, noting what parameters were paid attention to, and how they were transposed — pitch to star brightness, for example, and volume to distance.

Disquiet Junto 0236: Hello Jun(t)o

The Assignment: Say hi to the Juno Spacecraft by embedding Morse code in an original composition.

Screen Shot 2016-07-07 at 10.38.56 AM

Each Thursday in the Disquiet Junto group on SoundCloud.com and at disquiet.com/junto, a new compositional challenge is set before the group’s members, who then have just over four days to upload a track in response to the assignment. Membership in the Junto is open: just join and participate. There’s no pressure to do every project. It’s weekly so that you know it’s there, every Thursday through Monday, when you have the time.

Tracks will be added to this playlist for the duration of the project:

This project was posted in the late morning, California time, on Thursday, July 7, 2016, with a deadline of 11:59pm wherever you are on Monday, July 11, 2016.

These are the instructions that went out to the group’s email list (at tinyletter.com/disquiet-junto):

Disquiet Junto 0236: Hello Jun(t)o
The Assignment: Say hi to the Juno Spacecraft by embedding Morse code in an original composition.

In this project we’re going to send a friendly signal to the NASA probe, the Juno spacecraft, that just entered orbit around Jupiter. Well, we’re going to compose such signals. Sending them is a separate endeavor. We’re going to build on the “Say ‘Hi’ to Juno” endeavor, which had thousands of ham operators sending a message to Juno during its five-year voyage. The “Say ‘Hi’ to Juno” message was Morse code for “Hi” — that is, four dots followed by two dots (…. ..).

Step 1: Listen to the Morse code for “hi” (four dots followed by two dots) on repeat for a short time.

Step 2: Create an original musical composition that in one or more ways interpolates that Morse code.

Step 3: Upload your completed track to the Disquiet Junto group on SoundCloud.

Step 4: Annotate your track with a brief explanation of your approach and process.

Step 5: Then listen to and comment on tracks uploaded by your fellow Disquiet Junto participants.

Deadline: This project was posted in the late morning, California time, on Thursday, July 7, 2016, with a deadline of 11:59pm wherever you are on Monday, July 11, 2016.

Length: The length is up to you, though around one minutes seems about right.

Upload: Please when posting your track on SoundCloud, only upload one track for this project, and be sure to include a description of your process in planning, composing, and recording it. This description is an essential element of the communicative process inherent in the Disquiet Junto. Photos, video, and lists of equipment are always appreciated.

Title/Tag: When adding your track to the Disquiet Junto group on Soundcloud.com, please in the title to your track include the term “disquiet0236.” Also use “disquiet0236” as a tag for your track.

Download: It is preferable that your track is set as downloadable, and that it allows for attributed remixing (i.e., a Creative Commons license permitting non-commercial sharing with attribution).

Linking: When posting the track, please be sure to include this information:
