Bellbrook Marching Band competes in two different circuits: MSBA and BOA.
The Mid-States Band Association (MSBA) is a regional group of high schools from Ohio, Kentucky, and Indiana. The Marching Band usually attends 2-3 MSBA competitions each year, with Bellbrook hosting each September at the Bellbrook High School Stadium. At these events, which are hosted at local high schools, each band will perform once. The Marching Band also may compete in the MSBA Championship in November each year (click here for this year's site, Mason), which will have a preliminary competition in the morning/afternoon with a finals competition session in the evening.
The Bands of America (BOA) is a national program of Music for All. BOA organizes the fall championships across the country, including Regional, Super Regional, and Grand National Championships. BOA Regional Championships draw approximately 30 bands and are one day events with a preliminary competition in the morning and afternoon and a finals competition in the evening. They are held at large high school or college stadiums. BOA Super Regional Championships are usually two day events held at world class venues (ex. Lucas Oil Stadium in Indy) and draw 60+ bands. Preliminary performances are spread over two days with finals held the evening of day two. The Marching Band attends a BOA Regional and/or Super Regional competition each year.
The culmination of each performance season is the BOA Grand National Championships held at Lucas Oil Stadium in Indianapolis in November. This event draws 90+ bands from across the United States and is widely recognized as the premier marching band competition in the nation. The three day event begins with preliminary competitions held on Thursday and Friday. Approximately 35 bands selected for semifinals will perform beginning Saturday morning. The top 12 or so bands selected for finals will perform Saturday evening.
At competitions, each band is given a certain time block for warm ups and preparation for their show; then a 15 minute performance time slot, which is for the band to set up, perform, and exit the field.
