a group of people (usually around 15 to 30) that perform 5-10 minutes of
music indoors after marching season has ended. ages of people involved depend on the category (scholastic-highschoolers, independant-any
age up to age limit, open-mostly
college aged up to age limit, world-mostly college aged up to age limit).
ensembles usually are split into front ensemble (marimba, xylophone, vibraphone, synth, toys) and battery (snare, tenor, bass drums, cymbals) or in the case of concert ensembles, that have just front ensemble with no marching. the
music difficulty depends on the categories (or a mixture: i.e. independant open, scholastic A) and usually follows a theme or idea shown through the
music.
