Your rewards at a glance

The learning path has over a hundred steps. So that getting through them doesn't feel like a homework list, every round comes with something attached: XP, occasionally a level, sometimes a badge, and every day your streak. This page explains what each of those is, what it's for — and what it explicitly does not do.

Where to find it all

XP — what you've done

XP ("experience points") are the basic currency: "You earn XP with every exercise. XP raises your training level." After every round cori lists them individually — Round completed, First time bonus, New stars, Perfect!, Flawless!, Challenge bonus — and then counts your total up.

The point of it: even a middling round gets you something. The base points are awarded for every round you finish, however well it went. Only the bonuses reward accuracy. Doing badly never costs you XP — the number can only go up. The exact amounts are listed under How a practice round works.

Levels — the long arc

Enough XP lifts you to the next level. Each level demands a little more than the one before, as cori puts it itself: "XP raises your level. Each level needs a little more than the last." That's why the first levels come almost by themselves, while later ones mean real weeks.

That's deliberate: the early levels are meant to carry you through the first few days, when there's no skill to show yet. The bar tells you at any time how far along you are ("X XP to level Y").

Six ranks bundle the levels into titles:

"Ranks are titles that ride along with your level — pure flair." They don't unlock anything.

Badges — the milestones

There are 16 badges in total, and they aim at something other than your level: not quantity, but breadth and persistence. There's one for your very first note, for ten exercises, for fifty correct listening answers, for a faultless quick test, for a week in a row, for all seven scale degrees, for clean rhythm combos.

Three of them are tiered — one per branch (Ear Trainer, Rhythm Trainer, Voice Trainer). They climb through four tiers with the number of steps you've completed in their branch; in the collection you see them as a single badge showing "Tier x/4". That's why cori counts 16 and not more, even though there are more tiers.

Streaks — the daily habit

Your streak counts the days in a row you've practised. A single exercise a day is enough; it doesn't matter which. And because life gets in the way, you get two streak shields per week that automatically step in when a day falls through.

Of all the rewards, the streak is the only one that asks for something instead of giving something — and that's exactly why it's the most effective. Ear training doesn't get better through long sessions, but through short regular ones. Five minutes a day beats an hour on Sunday.

And in the choir?

Levels, streaks and badges are personal, but not secret: in the choir board you can see where you stand compared with your fellow choir members. How far along the learning path you are, which step you're playing right now or how you did in a round — nobody sees any of that there; only the rolled-up numbers are shared.
