FreeDrumlineMusic.com offers free drumline music for marching percussion groups all over the world. The site categorizes marching percussionists into 5 specific categories: Level 1, 2, 3, 4, and 5. These Levels are used to categorize an individual's playing abilities. These stickers offer a great way to reward students for their accomplishments and provide a simple, effective levelling system to improve their skills. Some programs recommend that students place their levelling reward sticker on their drum or music folder to act as a visual representation of their playing level. The levelling reward stickers offer students an incentive to not only improve their own skills, but other student's skills as well; this is the Karate belt for marching percussion.
