The thing is I'm taking Music as a subject. I am in my final year of highschool in the Caribbean and I am required to arrange a simple nursery rhyme and make a composition of my own by the end of the school year, which is very soon. Due to complications with teacher I was able to finally get one in December, but I worked extensively to try to fit 5 years on music theory in 5 months. So basically I must use all my knowledge of music theory to arrange Twinkle Twinkle into my own interpretation, and I was just looking for outsie help when I am not with my teacher. And I chose these instruments because they must be performed live and my island is very scarce with musicians. Sorry for the troubles for anyone trying to help.
