Plate XLIV. Coenopneumon contagiosum, the whole specimen.
Singing together joins a group by its air; each singer breathes what the others breathe out, so the breath that makes a choir one body carries its joy and its contagion by the same route.
To sing together is to share one breath, and all it carries.
behavior Gathers many small forms in a closed space and breathes for all of them at once, glowing as the song swells and darkening where something ill passes through.
provocation
Whose breath are you taking in when you sing with others, and what would you give up to sing alone?
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 mechanism, is
the dominant organ: the being's class, the one the idea could not lose and stay itself.
Which premise, if it were false, would kill this idea?
To sing together is to breathe one another's air; every singer takes in what the others have just given out, so a choir is one lung divided among many chests.1

Well-mixed room
What sets it apart from what it is not, and how does it keep that distinction?
It is set apart from people breathing in the same room by the song, which makes everyone breathe deep, in time and toward each other; it ends at the walls that hold the shared air.2

Close harmony
What must it feed on to work? What has to be present, noticed or supplied?
It feeds on a closed room, a song whose long phrases make singers breathe deep, and many voices close together.2

❦ dominant organ
How does it turn what it takes in into what it gives out?
Singing drives the breath deeper and louder than speech and sends out more droplets with it, so each singer breathes the others' breath, and whatever it carries, warmth, rhythm or a virus, passes through the whole choir in one rehearsal.2, 1

Fig. 5. Output
Superspreading event
What does it make possible, visible or knowable?
It gives the felt joining of a choir, many bodies breathing and calmed as one, and on the same breath the outbreak; of sixty-one singers at one rehearsal in 2020, fifty-three fell ill.1, 3
What part of it travels into other minds, ideas and fields, and by what vector?
It travels wherever people sing in one room, choirs, congregations and terraces, and in the rules made after 2020 that spaced singers apart and opened the windows.1

Fig. 7. Decay
Social distancing
What can it not digest, where does it fail, and what does it leave behind for others?
It cannot keep the joy without the risk, since both ride on the same breath; spaced, masked or behind screens a choir is safer, and breathes less as one.2

If it is right
Singers in a closed room breathe a measurable share of each other's exhaled air within minutes, more than people talking in the same room for the same time.
The sense of being joined that singers report grows with how deeply and how much in time they breathe, and so does the share of each other's air they take in.
Groups that sing outdoors or spaced apart report less of the joining than the same groups singing close together indoors.
Fruits
study
How much of your neighbour
During a rehearsal, mark each singer's breath with a harmless tracer and measure how much of it reaches the others, then ask each how joined they felt. If the two rise together, a choir's unity and its risk are one measure.2, 3
How much of your neighbour's breath is in your song?
artwork
A choir of one air
A choir sings in a cold, lit hall or a chamber of fine mist, so that each singer's breath can be seen leaving the mouth and the audience watches the breaths meet and mix into one cloud above the choir as the song goes on.
Where does your breath go when you sing?
story
The rehearsal
A short story told by the air of a church hall over one winter evening, the air that carries the warmth of forty singers, a hymn, a cough, and does not know which of them it should not carry.1
What does a room remember of the breaths that filled it?
bridge Both are rhythms that can be entered by a body without thought, and both are set from outside, breath by the air and the brainstem, music by the score.
friction Breath is private and automatic; music is shared and composed. Breath does not wait for anything, while music lives on waiting.
tension If a song decides when its singers breathe, whose rhythm is a choir breathing?
questions neither parent could ask
Does singing together make a group breathe as one body?
Can a song carry a way of breathing from one generation to the next, as work songs did?
What does a melody do to a heart that follows the breath it imposes?
pollination: What does a rhythm kept without thinking become when it travels the way music travels, from voice to voice?

Needs Breath's premise and Music's vector together. Heart and breathing rhythms of choir singers synchronize, and the synchrony follows the structure of the music. Close to the known pleasure of singing together, hence 2 on distance.
