How I built it
I built this because every sight-reading app I tried threw notes at me before teaching them, which just trains anxiety. Clefhanger introduces each new note first, then quizzes it, so you are always reading rather than guessing, and it widens from middle C to the full grand staff as you improve. The decision that mattered most was teach-then-test as a hard rule: nothing shows up in a quiz until you have met it.
