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:
Namdev, also transliterated as Namdeo and Namadeva, (traditionally, c. 1270 - c. 1350) was a poet-saint from Maharashtra, India who is significant to the Varkari sect of Hinduism. He is also venerated in Sikhism, as well as Hindu warrior-ascetic traditions such as the Dadupanthis and the Niranjani Sampraday that emerged in north India during the Islamic rule. The details of Namdev's life are unclear. He is the subject of many miracle-filled hagiographies composed centuries after he died.
Namdev's padas are not mere poems, according to Callewaert and Lath. Like other Bhakti movement sants, Namdev composed bhajans, that is songs meant to be sung to music. A Bhajan literally means "a thing enjoyed or shared". Namdev's songs were composed to be melodious and carry a spiritual message. They built on one among the many ancient Indian traditions for making music and singing. Namdev's bhajans, note Callewaert and Lath, deployed particular species of Raag, used Bhanita (or Chhap, a stamp of the composer's name inside the poem, in his case Nama), applied a Tek (or dhruva, repeated refrain) and a meter than helps harmonise the wording with the musical instrument, all according to Sangita manuals refined from the 8th to 13th centuries. The musical genre of Namdev's literary works was a form of Prabandha - itself a very large and rich genre that includes dhrupad, thumri, tappa, geet, bhajan and other species. In some species of Indian music, it is the music that dominates while words and their meaning are secondary. In contrast, in Namdev's bhajan the spiritual message in the words has a central role, and the structure resonates with the singing and music. The songs and music that went with Namdev's works, were usually transmitted verbally across generations, in a guru-sisya-parampara (teacher-student tradition), within singing gharanas (family-like musical units). Callewaert and Lath state that, "each single song of Namdev is a musical and textual unit and this unit is the basis for textual considerations". The unit contained Antaras, which are the smallest independent unit within that can be shifted around, dropped or added, without affecting the harmony or meaning, when a bhajan is being sung with music. In Namdev's songs, the dominant pattern is Caturasra, or an avarta with the 4x4 square pattern of musical matras (beat).
