| I think you've made a far more interesting kind of quiz than your original idea. With correct rhythms and rests, the quiz would essentially be "Can you read music and do you know these tunes?" But without these elements, the quiz tests your ability to recognize the song based on pitch and contour alone, which is a really interesting brain teaser. So I'm going to advocate for going in the other direction--take out the stems, barlines, and time signatures. |
