Jazz music has developed continuously since its beginnings
early in the twentieth century. The main instruments used in this musical style
originated with those used in military and marching bands. Today most instruments
in existence have been put to use in the performance of jazz music at one time
or another- including, in the case of one musician named Rufus Harley, the
bagpipes! However, there are some instruments that are much more common in jazz
today than others.
The main instruments of jazz groups
Supporting the music of a typical jazz group from every
period, the rhythm section traditionally consists of piano, drums and double
bass or bass guitar. The section is so named to distinguish it from the 'front
line' of melody instruments. A guitar may be used as part of the rhythm section
in larger bands or as a front-line instrument in smaller groups.
Reed instruments, including the various sizes of saxophones
and clarinets, are among the most important instruments in a jazz group, because
they tend to play most of the main themes and melodies.
Brass
instruments, especially the trumpet and trombone (occasionally the gentler -
toned flugelhorn), were actually used in jazz before the saxophone and are still
just as important.
