<p>My son is a music major this Fall as South Carolina, and he just took the AP Music Theory test. He loves all things music, and claims he will get a 4 or 5 based on how much he knew (he’s taken 6 other AP classes so should be a good judge of how he did). If you play, read, understand and have a passion for music, you’ll love theory because it helps you grasp where it all comes from. If you sort of like music but never took it seriously in high school, if you can’t read music, or if you don’t know much about the great composers, you’ll struggle and should consider a different class…</p>
