(STILL SECRET)
Design notes

Why not the saxophone
The saxophone's keywork assumes ten fingers and two thumbs. A nautilus brings up to ninety tentacles, and none of them has a sucker; they grip with ridged pads. Spread ninety tentacles over two dozen keys and you get congestion, not music.
Wind
A nautilus has no lungs. She breathes by pumping water over four gills and swims by jetting water out of a funnel, the hyponome. The Nautiliphone takes its wind from the hyponome: the same squeeze that steers her through the water sounds the reed.
Prior art: the water-blown hydraulophone. The arcanaphones file lists the other contenders.
Keywork
One key per tentacle is too many to build and too many to keep in adjustment. The drawing bundles the tentacles over a short, curved row of keys instead. Each bundle moves on its own, and the wind divides into three bores, so the instrument can sound chords, which a saxophone manages only by trickery.
Bell and float
The bore ends in a scroll that coils like her own shell, and the music escapes there. Beneath the body hangs a float, chambered like her shell and threaded by a siphuncle of its own. Her siphuncle trims her buoyancy; this one trims the instrument's, so it hovers in front of her and she never has to hold it.
The shell is a logarithmic spiral, but not the golden one, whatever the posters say.
Pitch
Sound travels about four times faster in seawater than in air, so a tube full of water sounds roughly two octaves above the same tube full of air. The Nautiliphone is therefore a transposing instrument. Its written key is to be decided by Suzanna.
Reading music
The nautilus eye is a pinhole with no lens. Sight-reading is out; the repertoire is learned by ear.
Concert hours
Nautiluses spend the day a few hundred metres down and rise toward the surface at night. All performances begin after dark.
Open questions
- A pad material that seals under water and does not mind salt.
- Premiere: whenever she is ready.
- Whether to tell the saxophonists: not yet.
