Question:
A marching band is a group in which instrumental musicians perform while marching, often for entertainment or competition. Instrumentation typically includes brass, woodwind, and percussion instruments. Most marching bands wear a uniform, often of a military style, that includes an associated school or organization's colors, name or symbol. Most high school marching bands, and some college marching bands, are accompanied by a color guard, a group of performers who add a visual interpretation to the music through the use of props, most often flags and rifles.
Traditional Style bands, also known as Show Bands, are marching bands geared primarily towards crowd entertainment and perform on football fields. Typically, they perform a routine before the game, another at halftime, and sometimes after the game as well. Competitive show bands perform only one show that is continually refined throughout a season, while bands that focus on entertainment rather than competition usually perform a unique show for each game. These shows normally consists of three to five musical pieces accompanied by formations rooted in origin from Patterns in Motion, a book penned by band director William C. "Bill" Moffit, bandmaster of Purdue University All-American Marching Band and University of Houston Spirit of Houston. A recognizable style of show band is the one fielded by historically black colleges and universities (HBCUs). HBCU bands utilize the traditional "ankle-knee" high step and music selections are largely based on R&B, hip-hop, and contemporary popular music. In addition to traditional drill formations, HBCU bands feature heavily choreographed dance routines as part of their performances. Many of these bands may have a twirler line and/or a dancer line, but not necessarily flag twirlers. One of the most notable depictions of HBCU bands is the film Drumline. HBCU bands are a significant part of African-American musical culture and HBCU bands often surpass their associated football teams in popularity, a phenomenon that is uncommon among collegiate and high school marching bands. In 1989, as part of the celebrations for the bicentennial of the French Revolution, the Florida A&M University Marching 100, one of the most prolific HBCU bands in the country, was selected as the official representative of the United States in the bicentennial parade. Another style of show band is that used by many of the Big Ten Conference marching bands, a semi-military and semi-corps style. These bands perform a show that is designed to entertain the audience, but feature more traditional symphonic styles of music (marches, film scores, jazz, or older pop music) as well as some contemporary music. Big Ten style show bands have been influential in creating some of the earliest marching band innovations, and the style is used in high schools throughout much of the United States. Most show bands of either type include the traditional military band instrumentation of woodwinds, brass, and battery percussion. Some also include the front ensemble keyboard percussion, and may also incorporate the use of a color guard for flag, and rifle routines as well as a dance line.

Question:
Harriet Tubman (born Araminta Ross, c. 1822 - March 10, 1913) was an American abolitionist. Born into slavery, Tubman escaped and subsequently made some thirteen missions to rescue approximately seventy enslaved people, family and friends, using the network of antislavery activists and safe houses known as the Underground Railroad. She later helped abolitionist John Brown recruit men for his raid on Harpers Ferry.
By 1840, Tubman's father, Ben, was manumitted from slavery at the age of 45, as stipulated in a former owner's will, though his actual age was closer to 55. He continued working as a timber estimator and foreman for the Thompson family, who had held him as a slave. Several years later, Tubman contacted a white attorney and paid him five dollars to investigate her mother's legal status. The lawyer discovered that a former owner had issued instructions that Rit, like her husband, would be manumitted at the age of 45. The record showed that a similar provision would apply to Rit's children, and that any children born after she reached 45 years of age were legally free, but the Pattison and Brodess families had ignored this stipulation when they inherited the slaves. Challenging it legally was an impossible task for Tubman. Around 1844, she married a free black man named John Tubman. Although little is known about him or their time together, the union was complicated because of her slave status. Since the mother's status dictated that of children, any children born to Harriet and John would be enslaved. Such blended marriages - free people of color marrying enslaved people - were not uncommon on the Eastern Shore of Maryland, where by this time, half the black population was free. Most African-American families had both free and enslaved members. Larson suggests that they might have planned to buy Tubman's freedom. Tubman changed her name from Araminta to Harriet soon after her marriage, though the exact timing is unclear. Larson suggests this happened right after the wedding, and Clinton suggests that it coincided with Tubman's plans to escape from slavery. She adopted her mother's name, possibly as part of a religious conversion, or to honor another relative.
