[2013·山东卷] George Gershwin, born in 1898, was one of America's greatest composers
He published his first song when he was eighteen years old
During the next twenty years he wrote more than five hundred songs
Many of Gershwin's songs were first written for musical plays performed in theatres in New York City
These plays were a popular form of entertainment in the 1920s and 1930s
Many of his songs have remained popular as ever
Over the years they have been sung and played in every possible way — from jazz to country
In the 1920s there was a debate in the United States about jazz music
Could jazz, some people asked, be considered serious music
In 1924 jazz musician and orchestra leader Paul Whiteman decided to organize a special concert to show that jazz was serious music
