TERRARIUM on iPad, Stage view, in the Intimate season: energy, patience and absence readouts, the 60-minute ceremony arc, a memory strip, the voices that are sounding, and the KEEP, HOLD, CAST, TIDE OUT and CLEAN keys.

An hour in eight movements.

Each season picks its voices, and how much space and memory they get.

Intimate, part one

The room has arrived. When you are ready, let the bed widen into Air.

5 to 8 min · first visit

Air

A phrase has come back to you a few times. Give it a pulse when it feels steady.

7 to 11 min

Ceremony, part one

The pulse has held a while. Thin it out and let it go still.

8 to 12 min · first visit

Frozen

This is the stillest place. Start something new from here when it calls.

6 to 10 min · the deepest point

Ceremony, part two

It is building. One more layer and it can open.

6 to 10 min · Ceremony returns, fuller

Storm

That was the peak. Let it fall apart slowly.

4 to 7 min · the peak

Dreams

Memory is carrying it now. Let the pulse go and come home.

5 to 8 min

Intimate, part two

Last tones. Let the freeze fade and leave the silence alone.
