Each rudiment below is one skill. You build evidence for it in two places — a knowledge check (Count It) and a trigger challenge (Copy the Sticking) — and this page combines them and tells you what to do next. The apps measure what a computer honestly can; your teacher verifies the actual playing.
What this page can and can't say. It reports knowledge (answer correctness),
pattern recall, and controller-sequence accuracy — the trigger evidence a browser can measure. It does
not claim you physically played the rudiment: grip, stroke, rebound, sound, and musical execution
are a teacher pass-off, shown here only as pending. Nothing leaves this device.
