Spectacular!!!

I have studied music theory off and on for several years and I have never learned so much about theory in such little time as I have using this app! I cant believe how thorough this experience has been and I am only just now about to begin lesson 3. My favorite part about it is its versatility to be able to apply what it is teaching you in so many ways. I also love that you can take all these tools with you anywhere! Wow. I want to recommend this to everyone!
