An orchestra that is never out of tune

Most toddler music apps are built so that pressing anything produces a triumphant noise, which is a fine trick for about ninety seconds and an exhausting one after that. This department takes the opposite view: the instruments are quiet ones, the tuning does the work, and the visual answer is designed to carry the whole room on its own.

That last part is not a compromise, it is the specification. Sound here is never on by default — a toddler who grabs a laptop in a waiting room should not broadcast to the waiting room. So every press throws an instrument and opens a ring of colour that expands and settles, and the room is complete with the volume at zero. Turn it up and the notes are a recorded kalimba, arranged so any combination of keys, including all of them at once with a forearm, resolves in key.

Rows of keys behave as sections, which gives two people something to divide. Take the top row, leave her the bottom, and trade. Play one thing and wait to see whether she answers it. Call-and-response is the oldest musical game there is and needs no explaining to someone who cannot yet talk. Two more places to stand: the drums, where every key is a low broad hit, and the music box, which you wind by holding a key and which gives back exactly what was wound into it.

Holding a key sustains a single swelling ring rather than stacking more sound, so leaning on the keyboard produces less, not more. Nothing escalates. Nothing loops on its own. Two seconds after the last press the hall is silent and still.
