In 1978, Brian Eno released Ambient 1: Music for Airports, a landmark album in ambient and electronic music. Although it wasn’t the first ambient album, it was the first album to be explicitly labelled as ‘ambient music’. Music for Airports was a continuation of Brian Eno’s experimentation with the tape machine as a compositional tool, a process he’d begun three years prior with 1975’s Discreet Music. It also saw Eno’s further exploration of generative, systems-created music, whereby Eno would focus on creating a system that would generate ambient music, something he continues to explore in the modern age with his range of iOS apps.
In this article, I’ll discuss how Music for Airports was created, and I’ll deconstruct and recreate the tracks 2/1 and 1/2. Hopefully, the article will demystify some of Brian Eno’s techniques, and give you some ideas about how to adopt some of his ambient music techniques yourself.
Brian Eno & Ambient Music
Brian Eno’s experiments with tape loops go as far back as 1973’s (No Pussyfooting), a collaborative album with King Crimson guitarist Robert Fripp. For the recording of (No Pussyfooting), Eno employed an early experiment in sound-on-sound tape looping, where he would run Robert Fripps’ guitar into two tape machines, that were then fed back into each other.
Fripp’s guitar melodies were recorded and then bounced back and forth between the two tape machines, creating longs, fading delays that would build up to create a dense soundscape. The length of the delay was controlled by the physical distance between the two machines.
Brian Eno’s tape experimentations continued with Discreet Music in 1975. The album’s 30-minute long title track was composed by sequencing his EMS Synthi AKS synth and recording it into a similar dual tape machine system, with the simple musical phrases repeating over a long period of time. This system utilised an EQ and delay effect before the tape machines, allowing Eno to subtly change the sounds in real-time.
Discreet Music uses two separate loops, one of 63 seconds duration and another of 68 seconds duration. Brian Eno found that using two loops of different lengths created a phasing effect where every repeat would produce different variations as the two loops interlocked in different ways. I wrote a separate article going more in-depth on the recording of Discreet Music, available here.
Recording Music for Airports
Music for Airports was released in 1978, though Brian Eno started working on it while working on David Bowie’s Low, in 1976. Part of it was recorded at the recording studio of Conny Plank, a legendary Krautrock producer, where he started by recording single notes sung by a trio of female singers, which he would later loop via tape machines. At a 1996 talk, Brian Eno described the recording of Music for Airports:
Music for Airports, at least one of the pieces on there, is structurally very, very simple. There are sung notes, sung by three women and my self. One of the notes repeats every 23 1/2 seconds. It is in fact a long loop running around a series of tubular aluminum chairs in Conny Plank’s studio. The next lowest loop repeats every 25 7/8 seconds or something like that. The third one every 29 15/16 seconds or something. What I mean is they all repeat in cycles that are called incommensurable — they are not likely to come back into sync again.
Brian Eno had previously recorded Before and After Science and Cluster & Eno at Conny Plank’s studio, and would go on to record Devo’s Q. Are We Not Men? A: We Are Devo! there too.
To compose the music of Music for Airports, Brian Eno’s experiments focused on using small recordings of music – sustained notes or 3-4 note phrases – and looping them at different rates, determined by the length of tape they are recorded on. The difference in tape lengths between loops would cause them to intersect in interesting ways; on each repeat, new phrases and variations on existing themes would emerge. Eno himself puts it best:
“The particular piece I’m referring to was done by using a whole series of very long tape loops, like fifty, sixty, seventy feet long. There were twenty-two loops. One loop had just one piano note on it. Another one would have two piano notes. Another one would have a group of girls singing one note, sustaining it for ten seconds. There are eight loops of girls’ voices and about fourteen loops of piano.
I just set all of these loops running and let them configure in whichever way they wanted to, and in fact the result is very, very nice. The interesting thing is that it doesn’t sound at all mechanical or mathematical as you would imagine. It sounds like some guy is sitting there playing the piano with quite intense feeling. The spacing and dynamics of “his” playing sound very well organized. That was an example of hardly interfering at all.“
Graphic Score
Music for Airports liner notes contains a graphic score designed by Brian Eno himself. Not a trained musician, and unable to read or write sheet music, Brian Eno instead used graphic symbols to denote each musical phrase or loop. Look closely and you can see individual symbols on each row, each spaced apart differently, reflecting the recording technique used to craft the album.
Brian Eno also designed the cover art for Music for Airports, as well the rest of the ambient series: Ambient 2: The Plateaux of Mirror with Harold Budd, Ambient 3: Day of Radiance with Laraaji and Ambient 4: On Land, each of which have map-like covers.
Deconstructing 1/1
The first track on Music for Airports is 1/1, which features a serene sounding piano melody interspersed with ethereal textures. 1/1 has been used in the films 9½ Weeks and The Lovely Bones.
The piano in 1/1 was performed by Robert Wyatt, a prog rock musician who started as the drummer in Soft Machine before pursuing a solo career. The piano recording has been run through an echo unit, looped and then slowed down, a process that Eno would have done by manually joining two ends of a reel of tape, and then playing it back on a reel-to-reel machine at half speed. Slowing down a tape machine causes the pitch of the musical content to drop, with half-speed causing a drop of an octave.
The piano loop in 1/1 features interplay between a traditional piano and a Rhodes electric piano. Here is the loop, and then the isolated piano and rhodes parts, it may have sounded at the original speed, before being reverb’d and slowed:
- 1/1 Original Speed 00:00
- 1/1 Piano 00:00
- 1/1 Rhodes 00:00
Once slowed down, the texture of the instruments change, becoming bassy and less defined. The echo effect gets smeared and stretched, creating an unreal ambience that is emblematic of the sound of Music for Airports. And this was some 45 years before the popularity of reverb and slowed versions on YouTube were a thing.
- 1/1 Slowed 00:00
- 1/1 Piano Slowed 00:00
- 1/1 Rhodes Slowed 00:00
The performance is mostly in the key of D major, with the Rhodes piano holding down D bass notes throughout. However, the final Rhodes phrase contains a C natural note, leading the music into modal D mixolydian territory.
Mixolydian is a mode, or scale, that contains the same notes as the major scale with one difference: it has a minor 7th instead of a major 7th. The Mixolydian mode has a more ambiguous sound than major, as it features a major 3rd and a minor 7th. The sound is still major, but with a less ‘sweet’ sound than in D major. The use of the Mixolydian mode is another facet that gives 1/1 it’s rested, relaxing sound; it sounds emotionally ambiguous.
Deconstructing 2/1
Music for Airports’ second track, 2/1 consists of a choir singing shapeless harmonies. There are no real melodies present, and the voices occasionally form chords, but there is no discernible structure. This song is composed of seven loops, all of different lengths, with each loop playing back a single, sung note. In the graphic score, you can see Brian Eno’s use of rectangles to represent looped tracks, with the spaces between them varying.
These loops have been recreated below, along with the approximate times that each loop repeats. Note that these times aren’t perfect, and the timings fluctuate throughout the piece, likely due to the way they were looped (the tapes were wrapped around chair legs). Some things to note here are:
- The C and high F loops are very close together to each other in duration (20.1 seconds and 19.6 seconds, respectively). They start out with the notes playing separately, and over time the notes gradually get closer together until they play back at the same time, almost as a chord.
- The D♭ loop has the longest length by a significant margin, and D♭ is also the most dissonant of all the notes in the piece, as it creates a semi-tone clash with C every time the two play together. The longer loop length for this note may have been a conscious decision by Brian Eno, or the composition may have just come out this way through experimentation.
Deconstructing 1/2
For the second track on Music for Airports, 1/2, Brian Eno uses eight short piano phrases recorded to tape to create the sense of a bigger composition, one that is again shapeless and without structure, but one that continually evolves as the piece progresses. Some of the loops are just single notes, and others consist of simple 3 or 4-note snippets, with one loop being an arpeggiated chord.
These loops overlap in different places upon each repeat, creating the illusion of new phrases and melodies, which are simply different combinations of the eight snippets. Looped for long periods, like the tracks 11:36 running time, allows for many variations and themes to emerge.
Click on the play icons below to start each individual loop. The dice button at the bottom randomises the loop times and the reset button reverts the loop times back to the original album times.
Ambient Approach
One way to get into this Music for Airports style of composition is to start using tape. If you can’t commit to getting big reel-to-reel machines, you can always start with cheaper cassette players. Some great online resources for cassette tape loops are Amulets, Hainbach, and Gemini Horror.
If you want to work with this style in your DAW, turn off the grid and start creating loops in seconds/milliseconds instead of bars/beats. In Ableton Live you can press ⌘ + 4 (Ctrl-4 on Windows) to turn off the grid, allowing you to create unquantized loops that work in a similar way to the tape loops described in this article. Create several clips of different lengths, set them all to loop simultaneously, and record the results.
To dig deeper into this style of tape loop ambient music, check out William Basinski’s The Disintegration Loops. William Basinski used a similar concept to Brian Eno, only the tapes he used rapidly deteriorated upon playback, causing the musical material to degrade over the length of the recording.

I got into this selection of music because of the TV Yoga dude, named Steve Ross. He would play Music for Airports near the end of the yoga class for final relaxation. If I recall 2/2 and FirstLight were also used.
Love this stuff. Thanks!
Airports Forever online. This is too much for free. Love it!
Very nice job. The interactivity is brilliant!
Another great study on this album: https://teropa.info/blog/2016/07/28/javascript-systems-music.html
For a likely influence on the graphic scores, see the early ’70s computer-programmed, flatbed-plotter-printed works of Manfred Mohr.

Looks like parallel invention to me. Notice that the similarity of both to standard musical notation which is itself inspired by written word and follows the same right to left, top to bottom convention of western books. Music is linear in time and is composed of layered portions. Graphing that information is going to look similar when you plot it left to right.
Hello,
It’s nice to hear this separated out, so thanks for the work you put into this and especially the audio setup.
The piece “1/2” is the first piece on the second side of the LP and so it is actually the third piece on the album.
I was going to mention that the arpeggiated chord wouldn’t sound for me in the original or the random mode, but it now does. Don’t know why that happened earlier.
Anyway, good stuff and I enjoy your explorations. Keep it up!
Rod
Thanks for the heads up, I’ll take a look at the player script at some point.
Fantastic article! TU!
Many thanks for this lucid, thorough and entertaining resource.
I likes this reflection but don’t forget Terry Riley’ role thinking repetition: the Revox that used Eno & Fripp was certainly Riley idea!
Something to do in the airport queue this summer.
You might even be able to get through the other Ambient series albums if you get hit with the delays at the moment
Using b as a flat sign in this day and age is an abomination. ♭ and ♯ exist; use them, please.
Otherwise, an excellent presentation!
Point taken, done!
Where do these symbols exist, please?
(Using mac keyboard)
Character Viewer and then Music Symbols. ♭ is unicode U+266D, ♯ is unicode U+266F
Thank you for this
Sitting under the fig tree later in this heat.. Not the band.. Will be glorious
Thank You ✨
Huh, I’ve been kicking around a desire to convince someone to make a perpetual music for airports machine and here I find it’s been done for 3 years already. Very grateful that you made this, and I will be adding it to my “adhd-cancelation toolkit” along with HatNote and Rain.Today
Great sites – I can recommend Generative.fm too.
I absolutely love this piece. I have linked to it in my most recent blog post about the influence of Brian Eno on my visual art. The chart in the liner notes has a direct connection to my visuals, and blew my mind. Thank you! https://iskrafineart.com/the-tarmac-residency-airport-landscapes-by-iskra-with-gratitude-to-brian-eno/
Thanks for sharing!
I have listened this album over and over since I first heard it in the 90s. This deconstruction is very nice and great and clear explanation what’s happening in the song. Thanks you for this.
For the track 2/1, I think you mixed up the visuals for low Ab, Eb and low F.
I think I did, thanks for the heads up, I’ve fixed it now!
Very inspiring article about very inspiring music and techniques. I shall now go and dabble with this in my VCV Rack, where the possibilities for this kind of music are endless.
VCV Rack is perfect for these kind of generative unsynced loops, I can also recommend Bitwig’s The Grid
This is outstanding. Thank you very much.
I likes this reflection but don’t forget Terry Riley’ role thinking repetition: the Revox that used Eno & Fripp was certainly Riley idea!
Nice read thanks. Love the sample player you set up here, feels like I’m Brian Enough:)
Hahahaha
Great job here. Such a beautiful record.
Good article, I combined this technique with Ableton’s random follow actions on some synth swells: https://www.youtube.com/watch?v=3eUYO_iGSCM&t=9s
Hola, excelente articulo. ¿Cómo puedo citarlo?
Great read!
thanks!
thanks!! <3
This is so great. Thanks so much for the great breakdown AND for including the loops. Pro move.
Thanks so much for the great article!! ss
This gives me a newfound appreciation for Eno. Also, does the 1/2 loop ever end? I feel like it’s been playing for 10 minutes now… ;0
the loop are set to keep going forever, or until you press the “stop all” button
Great article and loops. Thank you!
Wonderful, thank you so much for this.
Begs one to go to Earslap, open Otomata in one window, and Circuli in the other, run a few points and enjoy. https://earslap.com/
Circuli brings back memories, I used to put this on in the background a lot!
For your listening pleasure. Thanks for the loops.

Thanks for sharing Glenn, will put a link to this in the next newsletter!
Fantastic research. Thanks!
Eno’s Oblique Strategies cards have been digitized and posted here:

Thanks for this! Excellent analysis and beautiful samples!
Great article and wonderful to have the loop players to experiment!! Eno continued to use this generative approach I think, his gallery installations during the 1990s, for example, used several minidisc players with different loop lengths, and even his more recent ambient albums (such as Reflection) are still "systems music" based. It would be interesting to analyze in what ways his approach evolved over the years
This is great, and got me to become a supporter on Patreon! Thanks so much for putting this together. Like your previous commenter, some of this I knew, but not set out so clearly like this in a way that could be easily replicated, So I was messing around with this and tried putting the loops you provided onto different tracks of an Octatrack MkI, setting them to loop and not timestretch, triggered each sample, and I think it worked! Is that really all there is to it? Samples of varying lengths, looping continuously mixed together? Still not entirely sure about the "echo unit" part of Eno’s diagram. Is that just to say the original piano samples had a delay effect applied before they were looped? Or was the echo unit set up so that it re-effected the loop every time it looped, with the echo unit being "played" by Eno, manipulating settings slightly over time?
Yes, as long as your Octatrack isn’t quantising anything, that’s all there is too it! I only have the Digitone, which doesn’t do sampling, but it seems the Elektron sequencers are really good for this kind of music. I think the echo unit in the Discreet Music diagram is more of a reverb effect, to create that big, spacious sound.
This should all work the same on the Digitakt too. You can also do phase looping by taking the same sample, doubling it up, and then shortening one of the samples. This will move you into more of the Steve Reich types of loops.
For me, Eno is one of the most important producer alive. You explained very well how he was working, some things I knew, others were completely new to me. It
s great that you dive into the ambient pool. There is so much to discover. What I love about Eno
s albums from that time is the special sound they have, which probably owns a lot to the tape machines which where involved. Thanks alot, sir.Glad you liked the article, Eno is definitely one of my favourite artists!
