but a common show choir band consists of trumpets, trombone, alto/soprano sax, tenor sax, piano, and synthesizer, guitar, bass, auxiliary percussion, and a drumset. Some bands even include violins or cellos if the piece requires it. The size of the pit ensemble may vary greatly, but as a common rule of thumb, larger show choirs typically have larger bands to accompany them (anywhere from 3 musicians upwards of 30 in bigger schools). The band is usually not visually featured, but, occasionally, a show will bring out members of the band onstage to accentuate thematic elements in the show. A "tech crew" or "stage crew" is also standard with most show choirs. They handle things like lighting, sound, and the stage setup. During a show, the crew may have a great number of responsibilities, including helping performers change costumes, managing props, handing out microphones, running special effects, and other duties set out in the design of the show. Due to a stigma that the performing arts is a more feminine activity, many teenage boys are not attracted to participating in show choir. However, in order to achieve a full choral sound with rich melodies and tonal variety, show choirs need males to cover all vocal ranges. One study done by the Choral Journal claimed that many choir directors are simply resigned to having fewer males in their choir, but should make an effort to change. By reaching out to males and creating a more supportive community for high school boys, the hope is that more males will participate in show choir. With a higher number of males in the activity, a department can expect to see better scores at competition and higher team morale. Competitions Many show choirs participate in competitions, sometimes called "invitationals" (though most are not invitation-only events) or "festivals". These competitions are often held at the high school where the "host group" attends and sometimes performs as an exhibition, though some events are held at auditoriums or other facilities that can accommodate larger crowds and provide better acoustic performance. Competitions can be as small as a showcase of a few groups from the immediate geographic area or they can feature many groups from multiple states. Because of the vast difference in sizes of the competitions, they can last a single afternoon or span an entire weekend. Competitions may separate competing choirs into different divisions. These divisions are often
