Are you a music student who wants to improve your theory or ear-training skills? Our mobile app can help. It's not a theory lesson or video game. The app focuses on THEORY MEMORIZATION by using interactive audio flashcards on your mobile device. Understanding music theory is important, but memorization is not emphasized enough when it comes to this subject. Memorizing theory topics will not only help your grades in music class, it will make you a better musician by improving your composition and improvisation skills.
