Could SuperMemo be used to learn singing a melody?
This will be difficult. SuperMemo requires self-grading and this requires an ability to verify one’s own progress. For vocal training at the basic level, a teacher is indispensable. A beginner will often be unable to self-evaluate, for example, the accuracy of following a given pitch. However, a skilled vocalist can easily use SuperMemo to schedule his practice as soon as he or she is able to efficiently self-evaluate.
