Set the class goal

These settings apply to every student. Changing them re-scales everyone's current progress to fit the new goal.

Practice mode

Major keys

Minor keys

Major and minor are separate goals, tracked separately. The same staff can be correctly named two ways (no sharps/flats is both C major and A minor) — asking for both at once would make the question ambiguous, so a student works one at a time. Switch here once majors are solid.

How keys are added or removed

Window size

Number of recent answers used to judge accuracy. This automatically stretches longer as more keys unlock, so a bigger pool needs a longer accurate run before another key is added.

Minimum tested attempts on the newest key before advancing further

Stops the ladder from adding another key before the most recently unlocked one has actually been identified correctly on its own — not just averaged into an overall accuracy.
