I'm playing this one, and 'til now, I'm still unsure as to why it's grade 7. Does anyone know the key of playing it like a grade 7, or how I can such simple notes sound grade 7ish?

What piece are you talking about?

What instrument are you talking about?

I think he's talking about Dragon Dance by Polly Waterfield for grade 7 violin. It contains 2 pages of simple most single crotchets and groups of quavers.

I did it for my grade 7, it's difficult in terms of it's rhythm. It's changing nearly every bar, and the syncopation is difficult to coordinate with the piano, especially on the 2nd page. It took me quite a long time to accustomize to the rhythm.
