Subaru:  “There are three main types of tone-deafness. Inability to differentiate sounds, inability to make sounds, and inability to stay on beat. If you crush each of these problems one by one, even the worst tone-deafness can theoretically be cured. In other words, Emilia-tan can be fixed!”

Puck:  “Th-that’s a-meow-zing!” As Subaru raised his fist and lectured, Puck gave the expected cliché response.

Subaru:  The spiel Subaru had just given was actually a sales pitch he had seen once on a TV infomercial. The veracity of the claims was dubious, but it was at least a step up from trying to help her without a plan. Pitch, vocal cords, rhythm—those were the three main sources of bad singing, so by necessity, that was where the cure lay. “First, let me break down Emilia-tan’s problem so it’s easier to understand. From what I’ve heard, my best guess is the two main causes of her tone-deafness are pitch and rhythm. Her vocal cords shouldn’t be a problem because she was able to make sounds perfectly fine—also, she’s got a pretty face.”

Puck:  “Subaru, Subaru, tangent.”

Subaru:  “Oops, my bad—not that it’s bad to say that she’s got a pretty face—anyway, she can make sound without any issues. So she only has two problems to overcome: pitch and rhythm. Now repeat after me!”

Puck:  “Pitch and rhythm!” Puck added his voice to Subaru’s. They were both eager to cure Emilia’s tone-deafness.

Emilia:  “Hummmph.” Emilia sulked on the floor, hugging her knees to her chest. She was not even slightly motivated. Still, the telltale twitching of her ears showed she was listening to their conversation, which was adorable.

Subaru:  “Since Emilia-tan was able to appreciate Liliana’s music, that proves her ears can tell the difference between good and bad sounds. Since she can hear others’ singing okay but can’t hear her own, that probably means she’s unconsciously correcting her own mistakes in her head as she sings. Let’s fix that first.”

Puck:  “Easy for you to say, but how are we supposed to do that?”
