About
Clefarium turns sheet music practice into an adventure. Pop note bubbles floating through a living underwater world, connect your MIDI keyboard or use the built-in piano, and build real note-reading skills — one bubble at a time. Learn to read music inside a living aquarium. Clefarium is a music education app that makes sight-reading practice genuinely fun. Notes appear as bubbles floating on a staff — play the right note on your keyboard and watch them explode in a burst of particles. Play the wrong one and the bubble shakes back. The goal is simple: recognize notes faster, every session. All of this happens inside a procedurally-generated underwater world filled with fish, dolphins, crabs, and seahorses that keeps evolving as you practice. No two sessions look the same. Features: • Treble and bass clef practice • Whole, half, quarter, and bubble noteheads • Natural notes or sharps and flats — your choice • Connect any USB or Bluetooth MIDI keyboard for real instrument feel • Built-in on-screen piano — no extra gear required • Hint mode shows note names when you get stuck • Practice sessions with accuracy tracking and streaks • Save and reload your favorite aquarium scenes • Works on iPhone, iPad, and Mac
