The Orchestra consists of the string instruments; i.e., violin, viola, cello and string bass. There are four Orchestras at Kellenberg Memorial. One orchestra exists on the Latin School level for grades 6, 7 and 8, called the Praetorian Orchestra; and two orchestras exist on the high school level, for grades 9 to 12. The Phoenix Chamber Ensemble is for the more experienced musicians. The Firebird Orchestra is for the less experienced high school musicians. There is also an Instructional Orchestra for grades 6 – 9.
In conjunction with the Band and Chorus, the Orchestra participates in two public performances each year: The Christmas and Spring Concerts. Attendance is mandatory at these two concerts.
The Orchestra meets every day during the school week. In addition, all members of the Orchestra are required to take individual, weekly music lessons which are scheduled on a rotating basis during regular school hours. The cost for a full year of private lessons for members of the Orchestra is $600. The lessons are given by the director of the Kellenberg Memorial Orchestra and other string instrument specialists. Students are required to participate in the NYSSMA Festivals, so they may be eligible for the All-County Orchestra.
