"The cycleonium is a computer based music instrument. Every day objects like a bicycle and a bottle, and also a propeller are put in a new context and form the base of the sound design. They lose their conventional function consequently and have to be considered as indispensable parameters of this instrument." It was developed by Daniel Dominguez Teruel from 2007–2009 and built with the support of Chiron-Werke GmbH & Co. KG.
The physical and mechanical work that is required to make this sound-machine sound basically doesn’t differ from traditional musical instruments. For instance, a guitar: it sounds, respectively do we perceive it acoustically, if the strings are excited or the corpus is oscillated somehow or other. So the player expends energy and translates it into the instrument. The user and viewer of the cycleonium is to be made aware of that, in principle, musical instruments are nothing else than objects that only operate with a certain energy expenditure. The energy flow that is emerged thereby plays here a primary role. Therefore we use the word fluxus, but more in a semantically significance (lat. flux, fluidum = flow) than artistic aesthetics. Any kind of sounds require energy to sound. They have self-energy indeed, but it first has to be excited. Otherwise every sound is only a sounding abstraction (they aren’t a perpetual motion machine) that we don't hear. The player of the cycleonium produces, amongst others, kinetic energy that excites a propeller that simultaneously blows air on the aperture of a bottle: a pitched sound is audible.
