Context: The clarinet is a musical-instrument family belonging to the group known as the woodwind instruments. It has a single-reed mouthpiece, a straight cylindrical tube with an almost cylindrical bore, and a flared bell. A person who plays a clarinet is called a "clarinetist" (sometimes spelled "clarinettist")., Octurn is a Belgian polyrhythmic jazz ensemble led by Bo Van Der Werf (baritone saxophone and clarinet). Its lineup as well as the composers are changed for every album. They always play with at least 3 saxophones and from 2002 they have been playing with two basses and two drummers., Jeroen Van Herzeele ( born September 13 , 1965 ) is a Belgian jazz saxophonist . He was born in Zottegem . He plays in various bands such as Greetings From Mercury , Maak 's Spirit , Octurn , Tomas and Co , Ivan Paduart etc. . . He won the Belgian Golden Django in 1999 for best Flemish artist ., 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., The baritone saxophone or "bari sax" (commonly abbreviated "bs" or "bars" to distinguish it from the less frequently used bass saxophone) is one of the largest members of the saxophone family, only being smaller than the bass, contrabass and subcontrabass saxophones. It is the lowest-pitched saxophone in common use, and uses a mouthpiece, reed, and ligature that are larger than the tenor, alto and soprano saxophones, the other commonly found members of the family. The baritone saxophone is commonly used in classical music (such as concert bands, chamber music and solo repertoire), military bands, marching bands and jazz (such as big bands, jazz combos, etc.)., Jazz is a music genre that originated amongst African Americans in New Orleans, United States, in the late 19th and early 20th centuries. Since the 1920s jazz age, jazz has become recognized as a major form of musical expression. It emerged in the form of independent traditional and popular musical styles, all linked by the common bonds of African American and European American musical parentage with a performance orientation. Jazz is characterized by swing and blue notes, call and response vocals, polyrhythms and improvisation. Jazz has roots in West African cultural and musical expression, and in African-American music traditions including blues and ragtime, as well as European military band music. Although the foundation of jazz is deeply rooted within the Black experience of the United States, different cultures have contributed their own experience and styles to the art form as well. Intellectuals around the world have hailed jazz as "one of America's original art forms"., Blues is a genre and musical form originated by African Americans in the Deep South of the United States around the end of the 19th century. The genre developed from roots in African musical traditions, African-American work songs and European-American folk music. Blues incorporated spirituals, work songs, field hollers, shouts, chants, and rhymed simple narrative ballads. The blues form, ubiquitous in jazz, rhythm and blues and rock and roll, is characterized by the call-and-response pattern, the blues scale and specific chord progressions, of which the twelve-bar blues is the most common. Blue notes (or "worried notes"), usually thirds or fifths flattened in pitch, are also an essential part of the sound. Blues shuffles or walking bass reinforce the trance-like rhythm and form a repetitive effect known as the groove., Subject: jeroen van herzeele, Relation: instrument, Options: (A) bass (B) clarinet (C) piano (D) saxophone
