I love that music fabric and would try not to cut it up too much. Maybe use it and the other large floral for the center squares of an Ohio Star? Use the darks as the star points.
Another idea I saw was with a large black/white floral border that a quilter wanted to tie into her black/white/yellow quilt by colouring it.You could colour in some of flowers on your one floral and match that to whatever extra fabric you decide to add?
