Folk wisdom says perfect pitch is "inborn or never." That's only half the story. Children can develop full absolute pitch during a critical childhood window — especially with early musical training. But adult ears keep learning too: focused, repeated practice still sharpens accurate note recognition at any age. We built the app on the part of the science that works for grown-up brains.
