Jazz band [SEP] Vocalists
The definition of a jazz vocalist can be unclear because jazz has shared a great deal with blues and pop music since the 1920s. 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." Often the human voice can act in place of a brass section in playing melodies, both written and improvised. Scat singing is vocal improvisation with wordless vocables, nonsense syllables or without words at all. Though scat singing is improvised, the melodic lines are often variations on scale and arpeggio fragments, stock patterns and riffs, as is the case with instrumental improvisers.
