A key name appears. Find it and play it — without looking down at your hands. Feel for the black-key groups: two blacks means C–D–E, three means F–G–A–B.
The first key you press is your answer, and the clock is tight on purpose — looking down takes longer than it allows. Three wrong or slow keys and the stage does not clear, but the sweep always runs to the end.
Checking for MIDI…
This drill needs a real piano keyboard — there is nothing tactile about a mouse.
