HOW JAZZ MUSIC WORKS
Jazz is like a musical language. When the musicians play, it’s as if they are talking to each other in jazz language. Most jazz music is based on a tune or a theme. The tune might be made up specifically or it might be based on a popular tune. A jazz group, or line-up has two parts: the rhythm section and the front line.
THE FRONT LINE
Front-line instruments are the ones that play solos during a jazz piece. They are given this name because the players usually stand in front of the rhythm section. Front-line instruments include the clarinet, trombone and the right-hand side of a piano.
THE RHYTHM SECTION
The rhythm section is a part that keeps a steady pulse. It also plays harmonies for the front-line instrument to improvise over. Rhythm section instruments include the bass guitar, double bass, drums, and the left-hand side of the piano.
RHYTHM AND SYNCOPATION
Most rhythms have a regular pulse or beat. Normally the stress, or accent, comes on the first beat, in a measure. In Jazz, the stress sometimes comes on the second beat, or in between the main beats. This is called syncopation. A tension is created between the steady pulse and the syncopated rhythm.
JAM SESSIONS
When musicians get together without an audience and experiment with tunes, it is known as a jam session. It is during sessions like these that most Jazz evolves.
COMPOSING JAZZ
Although jazz involves lots of improvisation, there are some fixed elements in a piece. Instead of writing down every note, jazz composers provide a rough outline, usually consisting of a tune and the chords that go with it. Chords are two or more notes played or sung together. They are usually written as chord symbols, which tell the musician which chords accompany a tune. The musicians improvise around this hotline. Most jazz composers base their work on music they come up with during jam sessions.
