Musica teaches kids to read music notes by listening to them play a real piano.
Check that Musica has microphone permission (Settings > Musica > Microphone), the mic icon on the practice screen isn't paused, and the room isn't too noisy. Musica reacts only to piano sounds — voices and other instruments are ignored on purpose.
Each profile has a daily goal (set in the profile's settings). When a child completes that many notes in a day, that day earns a star on the Progress calendar. Stars keep the goal that applied on their day — changing the goal later never removes old stars.
