The Percussion League rules and regulations are a universal set of guidelines and structuring that has been adopted for use by the sanctioned events throughout each competitive season. These guidelines have been developed to provide an educational, competitive, and developmental process that is beneficial to students & performers of all genres, ages, and nationalities. Prior to each competitive year, show event hosts have an opportunity to propose new rules, as well as vote for changes and adjustments to these guidelines based on what is best for the growth of the collective community.
