Marching band is an athletic group of instrumental musicians who generally perform outdoors, and who incorporate movement – usually some type of marching and other movements with their musical performance. Instrumentation typically includes brass, woodwinds, and percussion instruments and the music usually incorporates a strong and stable rhythmic component suitable for marching. All marching bands use some kind of uniform, often of a military style, that include the school or organization's name or symbol, shakos, pith helmets, feather plumes, gloves, and sometimes gauntlets, shashes, and/or capes. In addition to traditional parade performances, many marching bands also perform field shows at special events or at competitions.

Marching bands are generally categorized by function and by the style of field show they perform. Increasingly, marching bands are performing indoor concerts that implement many of the songs, traditions, and flair from outside performances.

Dr. Phillips High School is a high school located in Orlando, Florida.

The area of Dr. Phillips, Florida is named after Dr. Philip Phillips, a physician who later became a Central Florida citrus magnate. He was responsible for several key innovations in the processing and packaging of orange juice. He owned thousands of acres of groves, stretching across nine Central Florida counties. One of his biggest groves extended from present-day Conroy Road on the north to the south end of the Sand Lake Chain, encompassing all of what is now Bay Hill, Orange Tree, Sand Lake Hills and Turkey Lake Park.

Dr. Phillips High School is perhaps best known for the fact that it is located directly across the street from Universal Studios Florida. Students can actually hear screaming roller coaster riders through the windows of some of the classrooms on campus.

March music originates from military, and often are played by a marching band. The most important instruments are various drums (especially snare drum), horns, fife or woodwind instruments and brass instruments. Marches and marching bands have even today a strong connection to military, both to drill and parades. Marches, which are played at paces with multiples of normal heartbeat, can have a hypnotic effect on the marching soldiers, rendering them into a trance, This effect was widely known already in the 16th century, and was employed to lead the soldiers in closed ranks against the enemy fire in the 16th and 17th century wars.
