Music Theory Classroom is a four-course, one- to two-year music theory curriculum designed for high-school and homeschool students. It covers the material studied by music majors in the first one to two years of college, but it is structured so that a diligent student can complete it in three 14-week terms. The four courses in the curriculum include: two Fundamentals courses which are intended to be taken concurrently, followed by Diatonic Harmony and then Chromatic Harmony. Each course has 28 lessons, so the recommended pace is approximately two lessons per week. For a more complete description of the curriculum, check the Music Theory Classroom dot com website.
