Music Theory part IV

So I've created another customized theory exercise.  This one has to deal with interval identification which is crucial for basic musical understanding.  I was able to create an exercise that the students would be able to use to identify basic musical intervals.  You can go here to see the exercise.  I've also taken a screen shot and put it below.

 As with the key signature identification exercise, the students can select their answer and get immediate feedback on their results.  If the students get stuck, then they can simple click the "reveal answer" button to see the correct response.
