We've heard a lot about climate change in the news over the past few years, but how many of us have actually heard climate change itself? Composer Arvid Tomayako-Peters takes listeners on a musical voyage back through five million years of Earth's climate history.


GELLERMAN: Well, twenty years from now Gleicians might be hearing this:

MUSIC: Arvid Tomayko-Peters “Vostok Blues”

GELLERMAN: This duet is composed from climate change records: data about carbon dioxide and ice temperatures put to music. Arvid Tomayko-Peters transforms geological data into sound using a computer program he created.

TOMAYKO-PETERS: In Geology, you have these layers stacked, one on top of the other and each one of them is a little bit different, so I approach this sort of like a score in music.

GELLERMAN: Arvid Tomayko-Peters just graduated from Brown University with a dual degree in computer music and geology. As part of his senior thesis he created the geo-music software. Living on Earth’s Ian Gray visited Arvid’s studio and produced this audio portrait.

TOMAYKO-PETERS: I’ve always loved science. And sort of the fact that I got involved in geology at Brown was an accident. I took a climate change freshman seminar and I was like, “yes this is fantastic.” I got into all that stuff like looking at ice ages and global warming.

TOMAYKO-PETERS: Then I started to write this meistrofranksnstein software, which is a multi track sequencer for scientific data instead of music.


TOMAYKO-PETERS: What we’re listening to is abundances of different elements then a column of mud from the bottom of a pond in Rhode Island. There’s twelve metals that we found in this mud that we’re concerned about such as chromium, arsenic and lead. Each metal is like a finger on a piano key. So in this case we have twelve fingers. You can see sort of at the end of the piece that a lot of the pitches get lower. That is an indication of less pollution because of less industry back 150 years ago when that sediment was laid down.

TOMAYKO-PETERS: So, I’m going to create a very little simple piece on the spot. I’m going to play you some data from the Vostok ice core in Antarctica. And turning that into music and I’m going to play it along side the record of global ice volume.


TOMAYKO-PETERS: So the string instrument that you’re hearing is the amount of carbon dioxide. And the tinkly xylophone-like synthesized instrument is the amount of ice. So the two instruments play opposite one another. When one is going down the other is going up through several ice ages. The time period that I’m going to play is the time that Homo sapiens has been in existence, the last about 195,000 years.


TOMAYKO-PETERS: Now when the stringed instrument, carbon dioxide increases, there’s not very much ice. And when the pitch of this xylophone-like instrument is higher, there’s more ice on the poles. The data that I’m using here shows this really tight correlation between the amount of carbon dioxide and the amount of ice at the poles on the earth.

The latest piece I’ve been putting a lot of work into was an interactive installation, where visitors would come in and hear eight deep ocean cores being played back as sound. And it’s a very sort of ethereal piece. You come in, you listen and there’s no notes. Everything is continuous tone and just constantly changing pitch.


Arvid Tomayko-Peters most recent project turned data from eight deep-ocean sediment cores into an experimental geo-music exhibition. A giant screen tracked data going back 5.3 millions years and flashed events from Earth's history that corresponded to the chronology of the data--like the birth of Homo Sapiens 188,858 years ago.

TOMAYKO-PETERS: Visitors come in and they can interact with a large timeline which they touch and go to any point in time. And what they hear are climate records played back on 8 speakers that surround them. And they see visuals that show them what’s going on in the climate then. You can see an ice age then everything turns blue in the entire room. And in warm periods everthing turns red. And what sort of evolutionary events are happening, weather when the first Homo sapiens are, where the first rhinos enter America, things that they might identify with somewhat.


TOMAYKO-PETERS: One of the wonderful things I think this music gives a listener a chance to do is relate to and experience this inconceivably long amount of geologic time that there have been. I mean a million years, you can’t even imagine that. And that’s just a tiny portion of the earth’s history going back 4.5 billion years. So, if you condense it down to something where you can experience that time in thirty seconds or five minutes it just sort of brings that time frame home, and makes you realize how absolutely short your existence is.


GELLERMAN: Our portrait of Arvid Tomayko-Peters was produced by Living on Earth’s Ian Gray.
