Ode to Joy (lead sheet, arr.) by Ludwig van Beethoven is one of the 527 pieces in the shared library that comes with Scoreflection. In the app, reading it and hearing it played back is free. Play it yourself and Scoreflection listens through the microphone and marks every notehead as correct, wrong, missed or mistimed — that part is the Practice plan, which needs you to be signed in.
