[Column] Ambient Techno / Deep Ambient 2

1. Sequel theme setting

Text: mmr｜Theme: About “deep sea acoustics” that redefines the act of listening to music

We treat Ambient Techno/Deep Ambient not as an ““acoustic genre,” but as a ““practice that redesigns the act of listening itself.” While assuming the history of its establishment, sound technology, and contrasting structure that were covered in the first part, here we shift our focus to the production environment, listening environment, playback media, and how time is used.

2. Design concept of long-term music

One of the important features of Deep Ambient and Ambient Techno is that they prioritize “playback time” over individual songs. Sustaining for 10, 20, or more minutes is a design imperative, not a lack of deployment.

When played over a long period of time, short-term stimuli and symbolic developments lose their meaning. Instead, subtle changes, fluctuations in density, and shifts in localization become the center of perception. This shows that music functions as an environment rather than information.

3. Boundary between loop and non-loop

The loops in Ambient Techno/Deep Ambient are not a gimmick to make you hear repetition itself. Rather, it is a device for artificially creating a state in which it appears that no change exists.

There is no perfect loop; there is always some fluctuation. Opening/closing of the filter, increase/decrease of noise components, length of reverberation tail. These minute differences are the only clues that give the listener a sense of the passage of time.

4. Production environment and sound characteristics

Deep sea ambient sounds are closely related to the production environment in which they are used. The quality of sustain is different between sounds that are precisely constructed in a studio and sounds that are improvised.

In highly improvisational productions, the sound is not too controlled, leaving a slight instability. This instability makes music not a static object, but an ongoing phenomenon.

5. Dealing with silence and silence

In Deep Ambient, silence is more than just a pause. The moment the sound disappears, reverberation and environmental sounds come to the foreground, and the listener’s attention shifts to the outside world.

For this reason, in many works, complete silence is avoided, and very faint sounds are sustained. What appears to be silence is actually filled with acoustics.

6. Playback media and sound experience

Ambient Techno / Deep Ambient’s character changes greatly depending on the playback media. Large speakers, headphones and small devices. Each creates a different depth.

In headphones, the physical pressure of the low frequencies is reduced, but the density of the internal space is increased. On the other hand, in speaker playback, the space itself becomes a resonator.

7. Intermediate area between work, sleep, and wakefulness

Deep sea ambient is suitable for areas that are neither fully awake nor fully asleep. In this intermediate state, music is not an object of attention, but exists as a background of consciousness.

What is important in this application is that the music does not induce emotion. Emotional ups and downs bring consciousness to the foreground.

8. Night listening culture

Ambient Techno/Deep Ambient has been strongly associated with nighttime listening culture. During times when visual information is reduced, the spatiality of sound is relatively amplified.

In works intended for nighttime playback, a configuration is often chosen in which the high frequencies are suppressed and the low and mid-low frequencies sustain for a long time.

9. Reinterpretation of fieldness

Deep-sea ambient music has the feel of a field recording without directly using natural sounds. What is important is not the sound source, but the imagination of the space.

Even if it is an artificial sound, if the sense of distance, reflection, and shielding are designed, the listener will perceive the non-existent environment as a real space.

10. Listener independence

In this kind of music, the listener is not a passive entity. It’s always up to the listener to decide how much attention to give and when to let the music become a background.

Ambient Techno / Deep Ambient is extremely democratic music in that it doesn’t force listening intensity.

11. Sustaining the digital age

In a streaming environment, music is easily skipped. However, deep-sea ambient music resists this immediacy. Because music cannot be judged in a short period of time, the act of continuing to play it has meaning in itself.

12. Complementary relationship with the first part

While the first part dealt with acoustic structure and history, this article focuses on practice and usage. Although both are independent, they share the same design philosophy.

13. Chronology

1990s: Popularization of long-form ambient works
2000s: Diversification of personal listening environments
2010s: Establishment of regeneration for work and sleep
2020s: Re-evaluation as environmental music

16. Summary

Ambient Techno / Deep Ambient redefines the act of listening to music. Deep sea acoustics is the optimized format for this and will continue to expand with applications.
