The curriculum is focused on reinforcing and refining fundamental wind and percussion skills. Members will be required to be prepared for each rehearsal. This includes having all materials and committing to a very rigorous practice routine. Students are REQUIRED to participate in either UIL Solo & Ensemble and TMEA All-Region contests unless seen otherwise by the Head Director. Students are required to participate in sectionals, one-on-one sessions and dress rehearsals that may be scheduled outside the school day. Due to the difficulty of the performance literature, students are strongly encouraged to participate in private lessons.

Percussion is a full year course dedicated to the molding of the modern age percussionist. Curriculum for the course is designed to develop the percussionist on all levels of instrumentation including mallets, world percussion, basic concert instruments, trap set,  and various marching instrumentation. The ensemble consists of 2 separate performing groups which all members participate in: the HS Drumline, & HS Percussion Ensemble. Students will be required to develop their skills in all areas, including all-region etudes, solo & ensemble literature, basic music theory, beginner and hybrid rudiments, and be proficient in percussive vocabulary. Students will also be instructed in care and maintenance of all percussion equipment. 

The percussion program at Terrell is very demanding. A significant practice routine will be required for optimal success. Students will be required to show up prior to the band on multiple occasions and will be needed for extra-curricular shows, send-offs, and other district requested activities. Percussionists in this section are required to attend all practices and performances as this section is not made up of a multitude of the same instruments, but instead it is a combination of multiple instruments that contribute to our success.
