@TheNightingalesStarling in my opinion GCSE and A level music are pretty irrelevant to people who want to study Music at Oxbridge. They are nowhere near the standard that is necessary to do well in a Music degree at those institutions. The reality is (and has always been) that it has never been enough for anyone studying Music just to do it through school, whether that’s a state or the very best independent school in the country.
The people studying Music at Oxbridge have been learning an instrument since they were very young, devoting thousands of hours of practice; they have excellent aural skills (requiring innate ability + experience, often gained through eg membership of a choir for years and/or preparation for the highest instrumental exam grades); an understanding of harmony which is above grade 5 theory level and light years ahead of any A level syllabus. There is also a music history element which uses the same skills as any humanities subject. Obviously music applicants will have the A level but if they are the calibre needed for Oxbridge it’s very easy for them.
The problem is that preparation for this starts in primary school, not secondary (with perhaps a few exceptions, eg singers). And it needs money- for private lessons outside of school, money for instruments, and importantly also knowledge about what is really required (ie the importance of regular practice and how to help your child with that, or again the money to pay for it).
Private schools offer instrumental lessons as a matter of course, they have ensembles, it’s normal for the children to be exposed to it and so the ones with an aptitude are identified early. By contrast, my son’s state primary had 1 term of recorder in year 2, taught by the class teacher who couldn’t read music, and none of his peers are learning an instrument. It is as fanciful to think that that could be enough to prepare someone for an Oxbridge music degree as to suggest that it would be enough for an applicant for English only ever to have read set texts for their exams.
I can understand why Tit hall want to encourage applicants for undersubscribed subjects and why they are targeting a group who are collectively much more likely to have the skills needed. It is extremely disappointing but a reflection of a reality that tertiary education can do absolutely nothing to change.
As a general point though and obviously just anecdotal, I went to a state school (grammar) and then read English at Cambridge 20 years ago. Of the 8 of us in my college there were people from Westminster, St Paul’s Girls, St Paul’s, City of London Girls, Hills Road, 2 x random other state schools I can’t remember, and me. 4 of us got firsts: me, Hills Road, other state school, St Paul’s girls (i.e 3/4 of the firsts were state schools); 2.1s were all the other private schools; 2.2 the other state school. So I don’t recognise what @cantabsupervisor was saying about the quality of state school students vs independent, though appreciate this may have changed over the intervening years.
