Hey, I did music performance last year (3 and 4), didn't get the best score but I do have some tips and advice I wish I knew before taking the subject.
- Practice theory and ear training daily. You can only really improve through daily practice, even if its just 5 minutes. some good websites are teoria and musictheory.net.
- know your skill level. Examiners aren't going to give you higher marks just cause you played something harder. Playing something at your level with appropriate articulation, tempo, technique etc will get you better marks than playing something beyond your level
- practice performing infront of people, after all, this is a performance subject. Examiners will assess you on how you communicate with others and performance decisions.
When I was in year 10 I also knew nothing about theory lol and thats ok. 1/2 theory literally starts from the basics of learning how to read music and slowly builds up to things like chords and scales. Your school will most likely assign a textbook or something to learn theory, but if you want to do more then you could try completing the ameb theory books and exam. You shouldn't stress about written theory, once you get the hang of it it'll feel like nothing.
because youre doing 1/2, focus this year on playing all sorts of pieces and improving yourself. 1/2 exam scores wont contribute to your SS so dont stress too much.
let me know if anything doesnt make sense lol, hope this helps
