By the way, here's a copy and paste of a structure I wrote in the past as a template for music UCAS applications (UCAS Conservatoires, you take out the books/reading, etc. and stick in more performance/composition-type stuff!):
"I generally suggest a five-point structure for UCAS personal statements. For music, I recommend something like the following:
1. Introduction. Since it can be hard to know where to start or what to write, I often advise music applicants (I'm a PS Reviewer here on TSR) to open their personal statement by talking about their earliest memories of their instrument and/or what attracted them to that instrument
This could also be a good paragraph in which to clarify what your main instruments are.
2. Performance/composition-related achievements/experiences/interests. This can be on your main instrument(s). Make sure these are noteworthy things and don't include anything in this paragraph that is quite old (I recommend only talking about experiences/awards from Year 10 onwards. Apart from the introductory paragraph, since you're talking about childhood experiences, obviously ). Make sure this is a mixture of solo and ensemble performing
3. Other music-related interests (e.g. particular eras in music history, world music, film music, etc.) NB. If you have done some super-curricular reading, mention it in this paragraph and put this paragraph as no.2 (and performance/composition-stuff as paragraph 3). Mention what you are interested in/have read, and why. For reading, make pertinent comments - don't try and summarise the whole book, just the main argument. Then express an opinion on the reading.
4. Non-music-related achievements. This is where you might put work experience/part-time jobs/volunteering, D of E award, sports teams - anything that's not to do with music directly
This paragraph should not be longer than either of your music-related paragraphs. Focus on transferable skills, rather than lengthy detail about the activity, etc.
5. Conclusion. This paragraph doesn't need to be that long but it MUST be good and have a proper ending sentence. You might conclude by saying what you're looking forward to studying, and remind the admissions tutors of why you would make a good music student at their uni! (Without writing it over-explicitly )
