Step-by-step explanation:
The Boston University (BU) established the nation's first College of Music; however, the provided reference material does not specify the date of establishment for this particular college. It is important to note that throughout history, there have been significant advancements in the field of higher education for the arts and music specifically, as can be seen in Ellison's enrollment at the Tuskegee Institute, which offered a top program in music in 1933, and the establishment of other institutions for Black students after the Civil War. Such institutions formed an essential part of Black higher education and included colleges that received support from the Morrill Land Grant Act of 1862, focusing on various areas of study including the arts.
