[3] The earliest use of the banjo in a jazz band was by Frank Duson in 1917, however Laurence Marrero claims it became popular in 1915.
Stylistically, this aspect of performance was shaped by its starting place, New Orleans,[6] as well as numerous other regions of the world, including other parts of the United States, the Caribbean, and Africa.
The American players Ted Lewis and Jimmie Noone were pioneers of the instrument in jazz bands.
[9] Swing clarinetists such as Benny Goodman, Artie Shaw, and Woody Herman led successful big bands and smaller groups from the 1930s onward.
[16] In their book Essential Jazz, Henry Martin and Keith Waters identify five main characteristics that identify jazz singing, three of which are: "Loose phrasing [...], use of blue notes [...], [and] free melodic embellishment.
"[17] Often the human voice can act in place of a brass section in playing melodies, both written and improvised.
[2] Scat singing is vocal improvisation with wordless vocables, nonsense syllables or without words at all.
The deliberate choice of scat syllables is also a key element in vocal jazz improvisation.
[19] A common way to incorporate improvisation is to feature solo performances from band members made up on the spot, allowing them to showcase their skill.
