Dixieland music or New Orleans jazz, sometimes referred to as hot jazz or early jazz, is a style of jazz music which developed in New Orleans at the start of the 20th century, and was spread to Chicago and New York City by New Orleans bands in the 1910s. Well-known jazz standard songs from the Dixieland era, such as "Basin Street Blues" and "When the Saints Go Marching In", are known even to non-jazz fans. With its beginnings in riverboat jazz, Dixieland progressed to Chicago-style jazz or hot jazz as developed by Louis Armstrong and others. The latter was also a transition and combination of 2-beat to 4-beat, introducing swing in its earliest form. "Chicago style" musicians used the string bass instead of the tuba and the guitar instead of the banjo to play a faster-paced, swinging style that emphasized solos. Hot jazz or Chicago-style jazz was also the current original music that began the Lindy Hop dance craze as it developed in Harlem.
