...Well, now somebody's giggling.

Aya giggles too. She starts folding up her written alphabet so she'll be able to tear it neatly. "Can you see? One whistle for yes, two for no."

Three whistles.

"...Sometimes?" guesses Aya. "Badly? Echolocation?"

On 'Badly', one whistle.

"Short range? But can you see your own keys?"

One whistle per question.

"Okay, so you won't have to memorize which letters I'm putting where." Aya remembers seeing a pair of scissors somewhere, and a jar of paste as part of some kind of kit elsewhere; she fetches them and cuts along her folds. "Okay if I glue these down?"

Another sigh-like huff, and then one whistle.

Aya pastes letters to keys, gently and carefully. She leaves gaps between them in the hopes of being able to eventually have a guess at what letter she's hearing without peering intently at the instrument. "There you go." She has more paper, ready to transcribe anything the instrument tells them.

"If I'm staring right at you, that fast is fine. If I'm distracted I won't catch it. I don't know about him. If you want to pick out some words you're likely to use a lot, we can use blank keys for those."

"I caught it all," he says.

Aya giggles. "How come you never sang to him, then?" she asks.

(He laughs.)

"...Is that just a coincidence, or do you prefer Piper to whatever you were called before?"

"It is definitely cute."

She plays a giggly ripple on some keys that aren't taken by letters, and adds a definitely non-giggle-sounding T E E H E E, perhaps to clarify.

"I could designate a key for signaling a toggle between communicating letters and making music for other reasons, if you like."
