Asymmetric time-line patterns are these rhythmic patterns
commonly found in Central and Western Africa.
They are intended for percussion parts of one single pitch (or at most
two – we’ll discuss more of this soon).
A time-line pattern is distinguished by the number of pulses within the
cyclical pattern, the number of hits, and the asymmetric grouping.
Below is the 20 pulse cycle broken in a 9+11 asymmetry. The measures on the left show the 11 strike pattern, while the left shows the 9 strike pattern. Notice how they complement each other. While these patterns are intended for a single instrument, a percussion part of two distinct pitches can play these opposing patterns.
In addition, these patterns can be phased into different variations.
While these patterns are not common at all in blues music, I do challenge the creative composer to use these patterns creatively in conjunction with different stylistic combinations.
