Our brain oscillates because rhythmic electrical potentials in the various cerebral areas need to synchronise in order to exchange information. These cerebral areas start to attune themselves when we focus our attention on something. Whereas the brain pulsates steadily when we keep our eyes closed, extreme amplitudes race across our cortex whenever we do some sharp thinking. This “cortical oscillation” appears to be crucial for our ability to recognise musical sequences. However, rhythms appear to enhance not only the perception of tempi, but also of changes in pitch level. According to a spectacular hypothesis, the brain’s rhythm has an influence on our consciousness. In any case, rhythms in the brain are synchronised more or less exactly with language. Thus, for instance, they aid our understanding of a continuing flow of speech. On the other hand, the role that rhythm plays in the processing of complex sounds is still comparatively little explored.
Are cortical rhythms the result of other brain activities or are they in fact the precondition for orderly neuronal processing? This question is one of the conceptual motors driving oscillare, to which the piece, however, will not propose a ready answer. Rather, by musical means it transports the listener to a place inside an oscillating brain, recreating the neuronal exchange of information through sound. So, please: switch off your brain and simply lean back.
