Hi, I have a candidate who is a grade 8 drummer he passed Rockschool grade 8 in year 9 he is now in year 11 and a very competent player and hard worker. He has composed a Rondo (Aos1) which is complete but really wants to compose a drum duet (Aos3) as this is his principle instrument for his second composition. Is this ok for him to do? I presume it is, but does anyone have any suggestions on a possible brief or what would be essential for him to include in the piece. His performances have been excellent so I am worried if this composition could meet the criteria and give him a composition mark he deserves. I have never had someone opt to do this before but presumably would be ok. Penny for your thoughts please. Thanks.
