This is a rubric I have used for years with my young band students when they perform a test. There is one rubric for woodwinds/brass and a separate one for snare/bells. The woodwind/brass grade is broken down into: note accuracy, rhythm accuracy, articulation, breath support, dynamics, tone quality, posture and embouchure. The snare rubric includes: rhythm, technique and dynamics. The bell has: rhythm, technique and note accuracy.
