Ear Navigator plays a note. You find it by ear on your piano, without looking, and the microphone checks you. A guided path starts with just a few notes and grows step by step.

1. 1Listen to a short chord progression — it sets the key.
2. 2Hear one note, then find it on your piano.
3. 3The microphone checks you. When you're ready, the path moves up.
