Musical polyrhythms are the simultaneous use of multiple conflicting rhythms in a piece of music. These rhythms can be independent of each other, or they can be interlocking in some way. Polyrhythms can be found in many different genres of music, including electronic music.
Examples of polyrhythms in electronic music include:
* Aphex Twin's "Windowlicker" which features a polyrhythm between the drums and the synths
* Autechre's "Foil" features a polyrhythm between the drums and the bassline
* "Hyperreal" by Flume ft. Kučka
* "Strobe" by Deadmau5
* "4Bit 9D API+E+6" by Aphex Twin
In a Eurorack synthesizer, polyrhythms can be generated in a few different ways:
1. Using a sequencer module: A sequencer module can be used to create different rhythms for different parts of the synth. For example, you could use one sequencer to create a rhythm for the drums and another sequencer to create a rhythm for the bassline.
2. Using a modulation source: A modulation source, such as an LFO or an envelope generator, can create different rhythms for different synth parts. For example, you could use an LFO to create a rhythm for the drums and another LFO to create a rhythm for the bassline.
3. Using a clock divider module: A clock divider module can be used to divide a single clock signal into multiple rhythmic patterns. For example, you could use a clock divider to create a rhythm for the drums and another clock divider to create a rhythm for the bassline.
Combining these techniques can create more dynamic and complex polyrhythms in a Eurorack synthesizer. However, there is no "right" way to compose a polyrhythmic piece. These compositions often result from happy accidents and random combinations of ordinary material that become extraordinary when their differing rhythms are combined.
