BEATS

An Experiment with rhythmic construction and polyrhythms

Beginning with the division of 56 beats into structures of seven, eight and fourteen; all of which fit into the fifty six beat set. A drum machine was programmed for a standard 4:4 pulse, another with a repeating rhythm of seven beats, another with a repeating rhythm of eight beats and a final machine was programmed with a repeating pattern of fourteen beats. Each pattern was introduced in pairs to show the beat changes; 4:8, 4:7, 4:14. Then combinations of three patterns were added together; 4:8:7, 4:8:14, 4:7:14. Finally, all four rhythmic patterns were added; 4:7:8:14.

Next a layer of patterns were created using a plucked string sound. This pattern echoed and used the same rhythms but gave them pitch values, moving in an arpeggio through a pentatonic scale. The same melody was used for each beat pattern, resulting in a complex tune. This set was introduced in the same way as the beats, sometimes accenting the new rhythm and sometimes filling in the missing beat pattern.

Then the melody was altered to a fifty six beat melodic line and adjusted to fit over the existing patterns.

A new polyrhythmic structure was created by examining the basic multiplication tables to see how more complex structures could befitted together. Patterns were created for 5, 6, 7, 8, 9, 11 and 13 beats. These were paired together in increasingly extended rhythmic sets of repeating figures; 5:6 over 30 beats, 6:7 over 42 beats, 7:8 over 56 beats, 7:9 over 63 beats, 6:8:9 over 72 beats, 9:11 over 99 beats, 11:13 over 117 beats and 9:13 over 143 beats. Repeats of each figure were looped to match up with the four – four pulse.

The first version was completed but the second attempt was discontinued.
