Thanks for the helpful advice. :) I decreased the size of the orchestra in that passage to flutes (ripieno), clarinets, horns, tuba, timpani, 2nd violin, violas, cellos, basses, and only the flutes and the solo violin and trumpet are playing above the low or middle treble clef. And I will have the trumpet play f like the rest of the orchestra. Think it will work now? :D
