GCSE students will have had experience of composing but if you have not don’t worry: the tasks are clearly structured and the style is entirely up to you – you don’t have to compose in the style of Bach if you don’t want to. The choice of performance pieces is also up to you, as long as they are approaching grade 5 (or equivalent) standard, then these will be at the right level for the course. Finally, you should be open to new styles of music from different periods and parts of the world because you will always learn something new and find new sources of inspiration.
