Hymne au Soleil, by Lili Boulanger, is the perfect on-field warm-up for your marching band. It can also be used as a brief concert fanfare or as a  warm-up for your band rehearsal. Also, take the opportunity of teaching your students about both Lili and Nadia Boulanger, sisters who had a tremendous impact on the course of 20th century music. When printing out the score use tabloid (11 x 17) paper."
