In this game, you can drag and drop the notes at the bottom to the empty staff above to build a scale. Many of the notes will remain unused. When you have finished building a scale you can click on the right arrow to move on to the next scale.
When you finish the last scale in the batch, click on Check to get feedback. Correct notes will add points to your score. Incorrect notes will deduct points from your score. You can play this game as many times as you would like. Good luck!
