You have been put in charge of a fifty piece marching band. Create a show for them! First, select your music: scroll over the each song to hear a sample. Then, drag and drop the drill cards* into the order you would like them in, and watch your show! (Step 2 is super laggy. Apologies. Also, the marchers enter from the top of the screen so the best first cards are the ones with a split in the middle.)
