The Royal Academy of Music provides instruction starting at the baby level (Junior Academy), while the senior Academy grants BMus, PhDs, and DMus in addition to the LRAM diploma. In the 1990s, the previous GRSM degree—which some students pursued and was comparable to a university honours degree was phased out. The University of London now offers the BMus degree to all undergraduates. Strings, piano, vocal studies (including opera), brass, woodwind, conducting and choral conducting, composition, percussion, harp, organ, accordion, guitar, and the majority of academy students are classical performers. Additionally, there are departments dedicated to jazz, musical theatre, and historical performances. Students from more than 50 nationalities attend the academy, which offers a variety of programs in opera, musical theatre, composition, conducting, instrumental performance, and jazz. King's College London and the academy have a long-standing association; in particular, the Department of Music sends students to the academy for instrumental instruction. In exchange, a large number of academy students enrol in King's extended academic musicological curriculum and a variety of humanities courses.
