Jazz Band 1-2, an audition only based ensemble, is a class geared towards preparing students for Jazz Band 3-4. These students have been playing on their instruments for 4 to 6 years and are most likely taking private lessons from a local musician. Many different styles of music are explored and there are several out-of-school performances per grading period. Instrumentation is limited to five saxophones, five trumpets, five trombones, piano, guitar, bass, percussion, and drums.

Any freshman student making Jazz Band 1-2 must enroll in one of the high school's three concert bands and be a member of a concert band for the entire school year.
