“Fifteen uncoupled simple pendulums of monotonically increasing lengths dance together to produce visual traveling waves, standing waves, beating, and random motion. One might call this kinetic art and the choreography of the dance of the pendulums is stunning!” Harvard Natural Sciences Lecture Demonstrations

This reflection that relates a pendulum’s movement with choreography as if it were a dance is the starting point of the project "Five movements on pendulum motion" by the composer Octavi Rumbau with the collaboration of the North American cellist Erica Wise. This project proposes a concert in duo, cello + laptop format, along with a multi-channel electronic device.

Since 2017, Rumbau has been working with the idea of pendulum movement as an algorithmic principle to generate complex textures whichcan lead us to unimaginable terrain. Specifically in this work, the idea is to create five new listening spaces based on different pendulum models that generate complex rhythmic figures, passing through static textures where time is diluted. In this way, the creation of spaces where the sonorous stimuli turn almost tactile, invite one to make a sensorial trip through a (perhaps better) continuously organic sonorous territory .
