PRIMA is a sight-reading trainer. It generates music you have never seen, listens through your MIDI keyboard, and scores every read. Difficulty adapts to hold you at the edge of your level, and progress is one number: a Reading Rating, like a chess rating for reading music. About twelve minutes a day.
One email when testing opens. Nothing else.
A generated exercise, mid-read. Played measures fade behind the cursor, so your eyes learn to live a beat ahead of your hands. That habit is the skill.
Every exercise is generated at exactly your level: phrase-shaped, cadenced, real music. Nothing repeats, so nothing can be memorized. The only way through is to read.
MIDI-first means every note you play is measured exactly, never guessed from a microphone. Each read is scored on pitch, timing, continuity, and steadiness, and rolls into your Reading Rating.
A session is a warm-up and four short reads, held near 85 percent success, where reading skill grows fastest. No falling notes, no streak guilt, no cartoons. A training tool, not a game.
Runs in Chrome or Edge on a desktop or laptop, with any USB MIDI keyboard. Made for intermediate players and adults returning to the piano, for when you have outgrown the beginner apps.
