　　From the blues① to pop

　　Early jazz

　　Today I will take a brief look at how Western music progressed② from the blues to pop. Modern pop music has its roots③ in the folk songs of black Americans ④held in slavery⑤. During the late part of the 19th century, black musicians used these folk songs to create a kind of music called the blues, because it had a tendency⑥ to be very sad. While the blues was popular⑦， as a musical format⑧ it lacked⑨ variety and was too sad and slow to⑩ dance to⑪. Thus, from the blues, there sprung up⑫ a faster, livelier kind of music called jazz.

　　Louis Armstrong, a black trumpet⑬ player and singer, was one of the fathers of jazz. Unlike most musicians who played the music as it was written, he would change the music as he was playing it to reflect his feelings at the time. Other musicians began to copy his style and the liberty⑭ he brought to his music⑮. The ability to adapt the music while it is being played⑯ is one of the major characteristics of jazz.
