When people talk about American popular music, they don’t just mean country music or rock music. There are two other types of popular music with national and international appeal that are basically American. One is Jazz. The other is a musical form associated with New York City theaters. Jazz originated from African religious and folk music. The themes and melodies of jazz music have historical origins. They came from songs sung by black Americans in church or at work. There have been different kinds of jazz music, the blues, ragtime, swing boogie-woogie and others. In playing jazz music, the performers blend rhythms and melodies with their skills of improvisation. Modern jazz music has developed into a complex musical style enjoyed more by musicians and older jazz lovers than by the general public. American theater has developed another American musical style. It is associated with a street in New York City, Broadway. Broadway musicals are dramatic productions in which the story is told partly by dialogue and partly through songs. The lyrics of these songs give background information about the story and express the feelings of the characters in the story. Many Broadway musicals have been made into movies that have been shown all over the world. "Oklahoma", "Sound of Music", "My Fair Lady", and "West Side Story" are some good examples. Songs from these musicals and others have translations in various languages that are sung around the, world. Many of them have become popular with people who have not even seen the musicals for which they were written.
