Composition seems very important, a thriving music community and resources will help foster this if required. Dd wanted an academic degree with a good community and opportunities for internships etc. It was a minefield starting out but she is a vocalist and really into her musicology /sociology, so was easier to narrow down from there.
Considered, Newcastle, Durham, Manchester, York, Sheffield,Nottingham, Birmingham (then decided didn't want to be far from home 🙄)
Bristol, Cardiff, Southampton (her firm) Surrey, Sussex, Royal Holloway.
Most of those seemed to have very supportive music communities and wide ranging modules. I was disappointed she wouldn't consider Bristol as I was told it has such a nice, tight knit community. Cardiff seemed great, she loved Sussex too although I wasn't sure on the community aspect there . Royal Holloway has specialism in Ethnomusicology. She wasn't impressed by Surrey at all it seemed facilities were lacking for students not doing Tonmeister course apparently..or she got that impression.
Can't say much about Oxbridge, apart from the reading list from Cambridge really helpful (Nicholas Cook's book is great) Reading and writing about Music will be required. Lots of good podcasts about too. I tried to get her to do the theory at grade 8 but wasn't having any of it.
I'm not musically inclined so was a bit clueless in helping her. Luckily she has excellent Music Teachers for A level and a mentor through her singing teacher who helped her prepare for auditions etc (Cardiff and Southampton both has auditions, great opportunityto visit).
