II. Rhythm
|
A. Basic Definition
|
|
1. |
According to the American Heritage Dictionary, rhythm is a regular pattern formed by a series of notes of differing duration and stress.
|
|
|
2. |
that part of the music which concerns how long or short each note is played
|
|
|
|
4. |
that part of the music that makes the listener want to to tap his/her foot
|
|
|
5. |
the “feel” of a tune (song); a tune’s “groove” (i.e., rock, funk, swing, salsa, etc.)
|
|
B. Jazz Rhythms
|
|
Jazz rhythms can range from simple to extremely complex. However, underlying even the most complex rhythms performed by each individual musician in a jazz group is an underlying pulse (the beat), i.e., that which makes the listener able to tap his/her foot with the music8. |
|
C. Tempo: The Speed of the Pulse (Beat)
|
|
1. |
The speed at which the listener (or the player) taps his/her foot is the tempo of that particular version of a tune.
|
|
|
2. |
Tempos in jazz range from very slow (ballads) to extremely fast (tunes that are “burning”).
|
|
|
D. Syncopation
|
|
1. |
the accenting of beats that are not "naturally" accented
|
|
|
2. |
stressing the notes that are on the up beat (i.e., when one’s foot is in the air – or up position – when tapping normally with the beat of the music)
|
|
|
E. Swing
|
|
1. |
a difficult-to-define rhythmic concept
|
|
|
2. |
for the musician, the definition of swing, among other complexities, is a manner of playing a steady stream of notes in a long-short-long-short pattern (watch What is Jazz video from 32:15 to 34:34).
|
|
|
3. |
for the listener (as well as the player), swing refers to the music’s buoyancy, rhythmic lilt, liveliness, and cohesiveness (watch What is Jazz video" from 31:40 to 32:12).
|
|
|
4. |
if a jazz performance has constant tempo (not slowing down or speeding up), rhythmically cohesive group playing, syncopation, and an upbeat feeling, it’s swinging

F. As Natural as Breathing
|
|
Through listening to jazz recordings (as well as live jazz), practice, and performance, jazz musicians internalize the rhythmic element so completely that it is as natural for them as breathing. |
|
G. What Makes Jazz, Jazz
|
|
The often subtle and varied use of a multitude of simple and complex rhythms, all interwoven extemporaneously into one cohesive sound, is, perhaps more than any other element, what makes jazz, jazz. |
