Writing a piece for a High School band to play..k
 

I am currently a High School Senior and for my capstone I am writing a piece for the band to play. Currently I play the flute and I am writing the melody in the flute key and transposing for the clarinets because my band has a limited number of flutes and clarinets so I wanted them to have the melody and then I would create the harmony around the melody but I am stuck with piece. Can someone help?
