<p>It would be good for you to KNOW the information contained in the AP Music Theory exam…however, you need to know, that as a music major, you will NOT receive any college credit for music theory at most schools. Why do you want to take the exam? It is important to know the material, but for a music major, the exam is irrelevant. You will take a theory placement test at your college that will determine where you will start theory. The AP exam in music will not be used (at least it’s not used anywhere that I have ever heard of for performance majors).</p>
