Note Recognition Drills for Piano
Build automatic note recognition with 10-minute drills, real songs, and instant feedback on any device or MIDI keyboard.
In plain English
TypePiano gives piano students short drills, real songs, and instant feedback, on a phone, a computer, or a music keyboard that plugs in. The practice is meant to make note names feel familiar, the way written words become familiar to a reader. Learners can start free and pay a student-friendly subscription when they want more, because the skill comes from regular practice with a fast check. The AI does most of the feedback and the billing. The person running the site still checks the drills, helps learners, and reaches them through search and student groups.
