The 2013 WGI Percussion Adjudication Manual & Rule Book contains all the necessary information instructors and judges need for the indoor percussion season. This informative book walks the reader through the process the design team follows in creating a percussion ensemble show and then translates that process into the scoring system. Detailed philosophy for each caption (Performance Analysis, General Effect, Visual, Artistry & Performance) as well as samples of each score sheet makes this mandatory reading for all those involved in creating or judging indoor percussion shows.
