Resonant Thoughts: Christopher Alexander on Dynamic Structures

“Things that are good have a certain kind of structure. You can’t get that structure except dynamically. Period. In nature you’ve got continuous very-small-feedback-loop adaptation going on, which is why things get to be harmonious. That’s why they have the qualities that we value. If it wasn’t for the time dimension, its wouldn’t happen.”

Christopher Alexander in Steward Brand’s How Building Learn (1995)

Arrows Of Attention: A Musical Phenomenology

A musical phenomenology:

a writing that sings its analysis,
generates its lexicon,
and blooms its concepts
from the sounds it encounters.

Writing that follows the paths of melodies and rhythm cycles,
feels the textures of sounds,
connects the substance with the style.

Writing that describes, evokes, conjures, summons, and elicits music’s affective presence.

Writing that revels in music’s sensual, tactile, transient, and resounding terrain.

Writing that takes music’s measure without counting.

Writing that foregrounds music’s negative space,
hears its inherent rhythms,
tracing what’s unsaid.

Writing that augments and amplifies music’s experience.

Writing that performs, not theorizes, music’s enchantments.

Writing that catches music’s vibrations,
alive at many levels at once.

Writing that suspends disbelief that music is magic.

A musical phenomenology:

a writing attuned
to musical energy,
mystery and aura,
structure and gestures,
grain and dimensionality,
surfaces and depths,
shape-shifts and metamorphoses.

Curating The Week: How To Get New Ideas, Attention, 40 Useful Concepts

An essay about how to get new ideas.

“The way to get new ideas is to notice anomalies: what seems strange, or missing, or broken?”

An article about monks and attention.

“We inherited the monkish obsession with attention, and even inherited their moral judgments about the capacity, or failure, to concentrate. But most of us did not inherit their clarity about what is worthy of our concentration.”

“One uncomfortable explanation for why so many aspects of modern life corrode our attention is that they do not merit it. The problem for those of us who don’t live in monasteries but hope to make good use of our days is figuring out what might.”

An article about 40 useful concepts.

“The mark of useful info is that it makes us act differently.”

Database: SG Lewis on Samplers

“Those old samplers…the audio quality would be degraded through dithering of the audio in the sample, in the sampler, or there’s a natural built-in bit crushing element to a lot of those samplers. Those distortion elements are introduced by feeding audio into a new piece of kit.

So the next couple of [production] steps were decreasing the quality of this audio. So taking a bunch of information out using EQ, over compressing it using OTT (…)

I was reading about the [1980s and 1990s] sampling and it was a case of trying to reverse engineer how sampling back then would sound in 2022—trying to replicate the shortcomings of those old samplers. The irony of it is that we have all this amazing equipment now and we spend a lot of time trying to make it sound shit again. Whether it’s the nostalgia or something about the audio that’s appealing to the human ear (…) It’s the same reason someone uses analog synthesizers or tape machines and stuff—there’s something about degrading the audio.”

Ways Of Tonal Evolutions

(Image: Casey Horner)

Listening to contemporary ambient music I notice that much of it is constructed from broad washes of sound, or what could be called tonal drones. Drones are sustained pitches that establish a mood, not a direction; they conjure a stasis, not forward movement. For many electronic music producers working in ambient’s orbit, a common way to make a drone is to engulf a tone in a sea of reverb. There’s a reason why the reverb’s Mix amount knob is labeled as a “wet/dry” control: with enough reverb a tone’s beginning and end blur into an oceanic unity, a continuous hum.

I enjoy some music built upon such spacious drones, but only when they make deliberate perceptual demands on my listening, rather than mere endurance demands. For the producer, being deliberate requires constructing the music that enacts evolving attentional shifts rather than stays in a single place. An ever-present problem with drones is that they induce a lazy listening. Of course, some listeners want exactly this: to use music as a backdrop for chilling out. 

Instead of tonal drones, I prefer chords that keep morphing into new constellations of themselves. These tonal evolutions make for active rather than passive musical textures, keeping my interest through the trajectories of their component pitches, as the notes dovetail around one another, leaving traces of their consonance and dissonance filigree, like the luminous dust of shooting stars. In terms of production practice, one way to create tonal evolutions is to generate an initial chord progression and then use it to seed other musical material–from chord progressions and melodies to drones and rhythms. Improvising chords or a melody on a keyboard (or other instrument) is a useful starting point because there’s multiple elements of uncertainty baked into the process: 

How long will you improvise for–four bars or sixty, 30 seconds or 5 minutes? What will the tempo be? Will you repeat motives you discover along the way, or continue onto ever-new phrases? Will you incorporate a lot of space between the notes, or aim for denser constructions? Will you play with a large or small dynamic range? Will your mistakes be left as they are, or corrected after the fact? Once you have an improvised a chord progression or a melodic line you have a tremendous amount of seed material to play with. Put another way: no matter how paltry you feel it might be, treat your captured MIDI or audio as gold. From here, consider six ideas for how to proceed.

Listen to the improvisation to find the good bits. It may be the case that somewhere in your improvisation there’s a gem of a chord sequence or melody that stands out, or stands on its own. Find this gem and copy its MIDI for use elsewhere, or render it to audio so you can play with that further. 

Consider the entire improvisation as the track-to-be’s structure. The unique ebb and flow of your performance could be an interesting way to structure a track. You may have implicitly delineated sections and an arrangement that just need to be fleshed out.

Derive other parts from the improvisation. There’s accompanying chords, bass lines, and bits and bobs latent in your improvisation. To start, copy the MIDI for the entire improvisation to other tracks. For example, a chord sequence can become a bass part if you pitch it down and mute all but one of the notes in each chord. Or a melody line might be traced in the sequence’s highest-pitched notes. 

Generate permutations of your improvisation. Play with your performance’s copied MIDI parts. Individual notes and chords can be pitched up or down, repeated, deleted, inverted, stretched out, or compressed. Practice permutation-making until it’s an inevitable part of your workflow. 

Record/resample your entire improvisation to audio. While MIDI is useful because it’s easily edited and can generate a thousand different sounds, audio is useful because it’s infinitely morphable. In a DAW, audio files can be processed in extreme ways, bringing the sound you began with far from its starting point. Plus, working with audio commits you to the MIDI you rendered: now there’s no going back to edit those MIDI notes.

Use your audio to generate new MIDI. One you have audio files of your original MIDI performance, you can use this audio to generate new MIDI. This audio-to-MIDI translation process is not perfect, which makes it fascinating: for example, the DAW often “hears” phantom pitches and out of key tones that aren’t in the audio, yet adds them in. You can use this new, not-quite-perfect MIDI file (derived from an audio file that was derived from your original MIDI) to seed other sounds.

In sum, these six techniques are useful for generating tonal evolutions as the basis of an active rather than passive ambient music.
