Please answer the following question: Information: - John Philip Sousa (November 6, 1854 March 6, 1932) was an American composer and conductor of the late Romantic era, known primarily for American military and patriotic marches. Because of his mastery of march composition, he is known as "The March King", or the "American March King" due to his British counterpart Kenneth J. Alford also being known by the former nickname. Among his best-known marches are "The Stars and Stripes Forever" (National March of the United States of America), "Semper Fidelis" (Official March of the United States Marine Corps), "The Liberty Bell" (used as the theme for Monty Python's Flying Circus), "The Thunderer" and "The Washington Post". - Polyrhythm is the simultaneous use of two or more conflicting rhythms, that are not readily perceived as deriving from one another, or as simple manifestations of the same meter. The rhythmic conflict may be the basis of an entire piece of music (cross-rhythm), or a momentary disruption. Polyrhythms can be distinguished from irrational rhythms, which can occur within the context of a single part; polyrhythms require at least two rhythms to be played concurrently, one of which is typically an irrational rhythm. - The "Maple Leaf Rag" (copyright registered on 18 September 1899) is an early ragtime musical composition for piano composed by Scott Joplin. It was one of Joplin's early works, and became the model for ragtime compositions by subsequent composers. It is one of the most famous of all ragtime pieces. As a result Joplin was called the "King of Ragtime". The piece gave Joplin a steady if unspectacular income for the rest of his life. - '' Weeping Willow '' is a 1903 classic piano ragtime composition by Scott Joplin . It was one of Joplin 's simpler and less famous ragtime scores , written during a transitional period in his life , and one of the few pieces that Joplin cut as a piano roll in a 1916 session . - St. Louis is an independent city and major U.S. port in the State of Missouri, built along the western bank of the Mississippi River, on the border with Illinois. The city has an estimated 2015 population of 315,685, and is the cultural and economic center of the Greater St. Louis area (home to 2,916,447 people), making it the largest metropolitan area in Missouri and the 19th-largest in the United States. - Ernest Hogan (born Ernest Reuben Crowdus; 1865 May 20, 1909) was the first African-American entertainer to produce and star in a Broadway show ("The Oyster Man" in 1907) and helped to popularize the musical genre of ragtime. - Sheet music is a handwritten or printed form of music notation that uses modern musical symbols to indicate the pitches (melodies), rhythms and/or chords of a song or instrumental musical piece. Like its analogs printed books or pamphlets in English, Arabic or other languages the medium of sheet music typically is paper (or, in earlier centuries, papyrus or parchment), although the access to musical notation since the 1980s has included the presentation of musical notation on computer screens and the development of scorewriter computer programs that can notate a song or piece electronically, and, in some cases, "play back" the notated music using a synthesizer or virtual instruments. - A melody ("singing, chanting"), also tune, voice, or line, is a linear succession of musical tones that the listener perceives as a single entity. In its most literal sense, a melody is a combination of pitch and rhythm, while more figuratively, the term can include successions of other musical elements such as tonal color. It may be considered the foreground to the background accompaniment. A line or part need not be a foreground melody. - Benjamin Robertson "Ben" Harney (March 6, 1872 March 2, 1938) was an American songwriter, entertainer, and pioneer of ragtime music. His 1896 composition "You've Been a Good Old Wagon but You Done Broke Down" is regarded as one of the early ragtime composition. In 1924, the New York Times wrote that Ben Harney "probably did more to popularize ragtime than any other person." Time Magazine termed him "Ragtime's Father" in 1938. - Scott Joplin (1867/68 April 1, 1917) was an African-American composer and pianist. Joplin achieved fame for his ragtime compositions and was dubbed the "King of Ragtime Writers". During his brief career, he wrote 44 original ragtime pieces, one ragtime ballet, and two operas. One of his first pieces, the "Maple Leaf Rag", became ragtime's first and most influential hit, and has been recognized as the archetypal rag. - Ragtime also spelled rag-time or rag time is a musical genre that enjoyed its peak popularity between 1895 and 1918. Its cardinal trait is its syncopated, or "ragged", rhythm. The genre has its origins in African-American communities like St. Louis years before being published as popular sheet music for piano. Ernest Hogan (18651909) was a pioneer of ragtime music and was the first to compose ragtime into sheet music. The composition was called "LA Pas Ma LA" and it was released in 1895. Hogan has also been credited for coining the term "ragtime". The term is actually derived from his hometown "Shake Rag" in Bowling Green, Kentucky. Ben Harney, who is also a Kentucky native has often been credited for introducing the music to the mainstream public. His first ragtime composition "You've been a good old wagon but you done broke" helped popularize the musical genre. The composition was published in 1895 but released in 1896. Ragtime was also a modification of the march made popular by John Philip Sousa, with additional polyrhythms coming from African music. The ragtime composer Scott Joplin ("ca." 18681917) became famous through the publication of the "Maple Leaf Rag" (1899) and a string of ragtime hits such as "The Entertainer" (1902), although he was later forgotten by all but a small, dedicated community of ragtime aficionados until the major ragtime revival in the early 1970s. For at least 12 years after its publication, "Maple Leaf Rag" heavily influenced subsequent ragtime composers with its melody lines, harmonic progressions or metric patterns.
