an important composer and jazz performer.
Jazz is a style of music that is not
much different from blues. Some of the instruments used in
jazz include the saxophone and the piano; but the most common and
classic of jazz instruments is the trumpet and other type horns.
There is not exactly a type of style in jazz as much as there is a way
you have to play your instrument to play jazz. As Nat Hentoff said,
"The true jazz singer does not try to be a horn, but rather to phrase and
glide and swing with the suppleness of a horn while not distorting or rushing
or mashing the lyrics. . . it is the art of being a horn like singer rather
than an artificial horn."
Playing jazz includes a lot of improvising, where - while staying within the main beat of the song - the player makes up their own melody as they play, bringing a whole new turn in the way the music sounds. Some of the most famous jazz singers are Billie Holiday, Louis Armstrong, and even Frank Sinatra is considered a jazz singer in some references.
