Plate LII. Postaudia expectans, the whole specimen.
Music leaves its listeners expecting, so the silence after it is heard as music; for a while a cough lands like a cadence and the street sounds composed.
Music goes on in whoever was listening.
behavior Lingers in a room after a sound has stopped, faintly glowing, and catches each small noise in its glow until it fades.
provocation
What did the world sound like in the minute after the last music that moved you?
Each draw is the being derived afresh by the current laws at another seed (laws §11); the chosen one leads (where they sit in the morphospace).
I Dissection
Each organ answers one question about the idea. The framed one, its output, is
the dominant organ: the being's class, the one the idea could not lose and stay itself.
Fig. 1. Kernel
Leading tone
Which premise, if it were false, would kill this idea?
Music leaves its listeners expecting, and the expectation outlives the sound, so the silence after a piece is heard as music; the room's small sounds take on tension and release.1

What sets it apart from what it is not, and how does it keep that distinction?
It is set apart from silence by what came before it, and from music by having no notes; it lasts only as long as the expectation does, seconds or minutes.1

Room tone
What must it feed on to work? What has to be present, noticed or supplied?
It feeds on the end of a piece heard closely, and on the small sounds of the room after it, a cough, a chair, traffic, rain.3

Metric grid
How does it turn what it takes in into what it gives out?
The ear goes on predicting what comes next after the music stops, and fits whatever it hears to the patterns the music set, so a cough lands like a cadence and a passing car like a closing chord.1, 2

❦ dominant organ
What does it make possible, visible or knowable?
It gives the minute after a concert, when the world sounds composed, and to those who listen closely a way of hearing the ordinary as music.3

Tacet
What part of it travels into other minds, ideas and fields, and by what vector?
It travels with the listeners out of the hall, and in the composers who wrote silence into their works so that it would be heard, Cage first.3

Fig. 7. Decay
Premature applause
What can it not digest, where does it fail, and what does it leave behind for others?
It fades as the expectation fades, and is broken at once by applause too soon or a ringing phone, which is why some audiences hold still to keep it.1
Silence gives the frame in which it is heard; Music gives the expectation that hears it.
Fig. 9. Bond
Al niente
What does each partner give the other, and in which direction does the claim run?
Music lends silence its expectation, and silence lets music go on after its sound; the claim runs from music into silence.1, 3

Fig. 10. Condition
Noise floor
Under what conditions does the bond hold, and when does it break?
The bond holds while the music was listened to closely and the silence after it is kept; it breaks with distraction, with noise, or with music heard only in the background.1

If it is right
In the seconds after a piece ends, listeners judge the room's ambient sounds as more ordered and more fitting than the same sounds heard before it began.
The effect is stronger and lasts longer after music with strong expectations, a tonal cadence, than after music without them.
It is broken by applause or speech, and listeners interrupted at once report it as a loss more often than listeners who were not attending.
Fruits
study
The minute after
Play listeners a piece and then a recording of the room's own sounds, and have them rate how ordered those sounds seem, before the piece and after it; vary how strongly the piece sets up expectation, and time how long the effect lasts.1
How long does a piece of music go on after it ends?
artwork
A concert for the after
A concert whose last piece ends with the doors opened onto the street and five minutes in which the audience, asked not to clap, listens to the hall and the city as the music left them.3
Can you hear the world the way the music left you?
interface
The kept silence
A setting for music players that leaves the room's own sound for a while after each piece, its length set by how the piece ended, instead of starting the next one at once.
What do you lose when the next song starts at once?
bridge Music is built of waiting, and a silence is the purest form of waiting.
friction Silence asks to be left alone; music always fills it.
tension Is a rest in music a silence, or the opposite of one?
questions neither parent could ask
How long can a pause hold a listener before it stops being music?
Does the brain hear the boundary between phrases in the sound or in the silence?
What would a music made mostly of rests teach about listening?
