Jazz is called the most truly American musical form. New Orleans, Louisiana, is often called the birthplace of American jazz. It appeared in the early 1900s. Most important musicians in jazz history came from New Orleans including Louis Armstrong (1900-1971), one of the greatest jazz musicians. Louis Armstrong created a new jazz style by improvising solos and performing them in an unusual style. Improvising is very important for jazz. Good jazz singers and soloists must improvise freely and skillfully. Louis Armstrong is said to be the inventor of a new vocal style when instead of singing words, Armstrong sang sounds like "de-de-de" or "lat-dat-da-da" to imitate various musical instruments. Later Ella Fitzgerald (1918-1996) used this style with great success, brilliant Ella, who was called the First Lady of Song and who became the finest woman jazz singer of all time.
The 1940s are known as the time of Big Bands. Their catchy music was everywhere and people danced to Big Band Music. The Big Band includes thirteen or eighteen musicians. The Big Band period gave the world wonderful musicians as Glenn Miller, Duke Ellington, Count Basie, Benny Goodman and others who played to full houses in dance halls and ballrooms across America. Jazz itself includes different styles, the blues, for example. The blues songs are slow and they are almost always about unhappy love or different troubles.
Today jazz is no less popular in the United States. Though it has changed, it preserves old jazz traditions.
Country music is American, too. It comes from old ballads and cowboy songs. Country music singers always use guitars, banjos and fiddles, they don't usually have big bands. The words of country songs are usually about unsuccessful love.
In the 1920s Nashville, Tennessee, became a centre for writing and recording of country music. During the 1940s and 1950s radio made country music more popular. It also began to change. It sounded more like the commercial music of the time. Still country musicians came to Nashville to sing and to record their songs. In the 1970s the "New Nashville" sound developed. Musicians started to use electric guitars. Country music has continued to be popular today. Some singers have gone back to the beginning of country music, they have continued to perform traditional country material. Meanwhile, new country styles are still developing.
