Treblemakers are a small, select all-women’s ensemble performing primarily a cappella vocal jazz, pop and show tunes. Membership is limited to juniors and seniors by audition only. Students requesting consideration for this group are assessed each year in January. Members must also sing in the Symphonic Choir. The Treblemakers perform regularly at functions outside the school in addition to required evening concerts as dictated by the Vocal Music Department schedule. Attendance is required at all extra practices and participation in concerts is mandatory. There are performances outside of the school day. Failure to attend these performances and/or performing in an unsatisfactory manner will result in disciplinary and/or academic action.
