How it works

Nothing is ever too high.

The whole idea behind Yodelope is small enough to explain in two parts: it finds where a child's voice sits, then it meets them there. Here's how each part actually works.

Part one

Finding your child's voice.

Before the first real song, every new singer plays a ninety-second calibration game.

A note, then an echo

Yoli sings a short tone. The child copies it back. A balloon on screen rises or sinks to show how close the match was — six to ten rounds, walking from a comfortable middle note outward.

Every try counts

If a note doesn't land, the game never frames it as a mistake — it just tries a gentler version and moves on. A child can skip calibration entirely and get a safe default range.

A buddy, not a number

The result isn't shown as a number or a grade. It's a match to one of five Range Buddies — a character, not a score. Meet them →

Part two

Singing along, with feedback you can see.

Once a range is set, every song is arranged to fit it — so a child is never straining for a note that's out of reach.

During a song, the lyric line scrolls across the screen in Andika — a typeface designed by literacy specialists for early readers, with letterforms like a and g shaped the way a child actually learns to write them. Above it, a lane shows the target notes as they come, and a dot shows where the child's voice is right now.

When the dot sits on the note, it's on pitch. When it drifts, a gentle chevron nudges up or down — never a buzzer, never a red X. Nothing in Yodelope treats an off note as a strike against the child.

Why it matters

A song shouldn't be a ceiling.

The problem with one key

A lot of "kids' karaoke" is really adult karaoke with cartoon characters — one fixed key, written for an adult range. A young child ends up straining and shouting to reach notes that were never written for a child's voice in the first place.

What Yodelope does instead

Every song in Yodelope is arranged so it's available in the key that fits a child's own range — the one found during calibration. The song a five-year-old sings and the song a nine-year-old sings can be the same title, comfortably, in two different keys.

A range can change

Voices change as kids grow. Calibration can be re-run any time from the Grown-Ups Zone, and nothing about a child's progress or coins resets when it is.
