The Grayson Wind Ensemble, also known as "Mastery Band", is the premier ensemble of the four concert ensembles at Grayson High School.  Membership is limited to students in 10th-12th grade and is determined through an audition process that takes place in December each year.  Students obtaining the highest scores on their instrument at the conclusion of that audition process will be sorted into the Wind Ensemble based on the instrumentation needs of the ensemble for the next academic year.  Students in this ensemble will have very high expectations placed upon them, face rigorous course work, and perform some of the highest caliber wind band literature for bands today.  Students in this ensemble will perform literature from the GMEA Level 5 and 6 list.
