Great learning tool!

I wish I could give this app 6 stars! I was beginning to think I was incapable of learning intervals. But like everything in musicianship, it takes practice, and this app makes it easy (and dare I say, fun). I turn it on while doing chores or walking, saving precious practice time at the piano. I found it good in the beginning to focus on one interval at a time, learning to sing them back aloud. A great learning tool that I highly recommend.
