This pendulum formula has had a significant impact on science and humanity in general (not least, giving an accurate measurement for ‘g’). It has also been at the heart of much of my music and arts/sci work for the past couple of years...

There are a vast number of different types of pendulum experiment. The original Pendulum Wave experiment, where multiple uncoupled pendulums of increasing lengths move together to produce visual traveling waves, standing waves, phasing, beating, and quasi chaotic motion, is the subject of physics, kinetic arts and desk toys! By focusing on experiments carried out by Galileo, Newton, Huygens, Foucault and Cavendish (Baker, Gregory L. 2009), I am developing large-scale physical sonic sculptures that will be designed and constructed enabling the early wave visualisation to be studied and analysed. Methods of analysing movement and extracting data from the swinging pendula will be investigated via video or other forms of motion tracking.

The periodic nature of the pendulum will be compared to the work with pulse, phase and time of composers such as Nancarrow, Cowell, Reich and Ligeti.

I am fascinated by the periodic nature of sound that can be seen through astronomy, time and, not least, the human psyche.
