/why
Why we made it
Most music games are rhythm games — tap exactly when the note hits. Toccata is different: it tests your EAR, not your reflexes. You hear a melody once, then must play it back from memory. Inspired by ear-training drills, but wrapped in an addictive mobile game with social features (live multiplayer, chain composition) and a Concert Hall that auto-orchestrates classical masterpieces.
