"You could sing a song like I did, or recite poems, or tell stories! Short ones, since the cylinders can't hold much."

After some internal discussion, they decide to sing a dockside shanty.

And it is recorded to wax form and she plays it back for them.

Haha, that's great!

"I'm thinking maybe they would be good for restaurants and places like that to play music, and musicians could sell their cylinders - maybe somebody would want a booth where you can record your voice and hear it played back, people's voices sound different to themselves -"

Those all sound like good ideas. Not that they know, really, they move crates for a living and haven't before had cause to entrepreneur before.

"Do you know if there are any - invention fair or convention sort of things anywhere?"

There's the summer festival in like a week?

That'll do! She looks into getting a booth.

The organizing committee is taking applications! Name, interest, sponsor (if applicable)?

Tarinda, a new invention she is calling soundwriting, no sponsor.

She can have a side street booth. Here is the location. The committee is not responsible for guaranteeing any level of visitor count or the safety of her booth should she decide to leave it unattended et cetera.

That's fine.

She makes lots of cylinders and attempts to rush a second device.

Her workshop gets a visitor before the festival.

"Evening!"

"Hi. I heard you made something."

"I did!" She puts on the cylinder of her singing.

"How does it work?"

"Sound is really the same thing as vibration! If you have something set up to vibrate in a way that leaves a mark, sound will make it do that. And if you have something set up to vibrate according to the marks, then sound happens."

"Huh. I hadn't thought of it like that before."

"It's really cool! If you want to record something I got curtains to reduce background noise and you can buy a cylinder use. They can be reused sort of, shaved down, but then they don't hold as much, so I have to charge."

"Can you only record on one at a time?"

"I could set it up to record more than one cylinder at once! These aren't like that, they're prototypes."

"Can I see one?"

"Sure." She shows her a phonograph, sets it playing her own little song.
