Jazz music is considered as a musical genre which combines improvisation, back beats, swing notes and blues with brass instruments. Classes in jazz music is popular among the young and the old, but more specifically in the more mature students who are also taking up some German lessons in language schools. These elements are combined in a variety of ways to create different types of jazz music.

One of the earliest types of jazz music would be New Orleans Dixieland jazz. This type of jazz was able to create jazz standards like When the Saints Go Marching In. New Orleans Dixieland jazz dominated the music scene during the early 20th century. It was known for the ragtime jazz sound that it has, which was played on top of a rhythm section, quite unusual for jazz music performances. These rhythm sections usually included guitars, drums and banjos. Many language schools that offer German lessons also teach a bit of New Orleans Dixieland jazz.
A popular type of jazz music would be swing. This jazz musical genre dominated during the 1930s and during World War II. This musical genre was the primary form of popular music in America back then. It was the genre that introduced exuberant big bands to the US. It was named after the strong swing notes which were played in a unique jazz style. These swing notes involved a style where the first note in the rhythm is extended over the second note and then improvised.
A jazz music movement that was popular from the 1940s through the 1960s would be bop. Bop was a type of uptempo jazz that was insistent on harmony. Several jazz music legends such as Charlie Parker, Dizzy Gillespie and Thelonious Monk were popular for this type of jazz music. However, many listeners soon found bop to sound a bit incomplete and somehow rushed, which eventually led to a new jazz music type that had intricate melodies. This jazz music type was called cool jazz.
Cool jazz was popular in the 1950s and the 1960s. It had an easy tone, which avoided the abstract quality of bop. A jazz performer who played cool jazz would be Miles Davis. Another jazz music type which evolved from bop would be free jazz. Free jazz made use of less composition and of loose harmony and tempo. One of the well-known free jazz musicians would be John Coltrane. This is one of the most popular jazz music genres even today that older students of German lesson (Deutsch Kurs) and classes of a good language school (Sprachschule) also take.
During the 1960s and 1970s, Latin jazz emerged. it consisted of rhythms that had African and Latin American roots and were usually played using instruments such as timbale, guiro, conga and claves. As for the claves that had jazz and classical harmonies, the instruments that were used included double bass and piano.
Soul jazz was another jazz music type that was popular in the 1960s and 1970s. It was actually developed from hard bop jazz music that incorporated several strong influences from gospel, blues and rhythm and blues. Soul jazz also generally emphasized repetitive grooves along with melodic hooks. The improvisations soul jazz used were also usually less complex compared to the other jazz styles.
Although jazz music continued to be popular through the 1970s, the jazz community significantly shrank and eventually split during the 1980s. There was, however, a mostly older audience that retained an interest in the traditional and the straight-ahead jazz styles. Today, the elements of jazz music have been integrated in other genres of popular music.
Many colleges and universities today offer some jazz music classes with their course offerings. Most of these students usually belong to the more mature crowd who are also taking up a German lesson or class. Jazz music courses are also sometimes offered in a reputable language school that teaches German lessons and German courses.
