<p>The difference is in the depth of study required in musicology for a BA (and the faculty - BA faculty will be mostly PhD’s, often with composers teaching theory). A BA in music at Harvard or Berkeley, for example, requires more courses in music history, and some in ethnomusicology, and fewer in some of the theory requirements typical for a BMus. A BA degree also requires more academic courses overall. The tradeoff is fewer performance requirements, and many are simply extracurricular. Even at Oberlin, where there is a large academic faculty, especially in theory, the requirements for a BMus. in performance includes only 1 (2 for piano) upper division theory and upper division music history (2 for piano) course of your choice, and no ethnomusicology is required. It is possible to double major in musicology (at Oberlin you can’t do a double degree in music performance and music history, though – it is a double major BMus), or just take the courses that are of interest and are not required. But the courses outside the major in the college would be less extensive.</p>
