Pattern Perception Pattern Recognition

A Pocket Installation: sequenced alert electronics

An exert (3mins 49 secs) of Pattern Perception Pattern Recognition recordings made at Atavistic ratchets, a week of sound installations by brownsierra (Pia Gambardella & Paddy Collins) 21-26 July 2003

12 Piezo buzzers 4 Sequencers 16 Batteries

4 Battery holders 4 Switches 4 Boxes

Four groups of three piezo sounders independently sequenced with differing simple patterns and tempos the components are placed in response to the shape and acoustics of the particular space within which it is presented.
The sequenced buzzers on each board create patterns, which phase in and out with each other. Within psychological testing for pattern perception it is usual to use metronomic sounds of equal spacing volume and pitch, what we attempt to create in this piece using the four overlaid sequences is to find out if the listener will respond differently to the sequence of sounds.

A steady train of buzzes, when every buzz is the same as the other and every sequence constantly repeated, yet no one hears it as a steady train. The listener can impose a rhythmic pattern of his own choosing. Two different listeners can be exposed to exactly the same steady train of acoustic pulses, yet hear them in entirely different patterns this can be seen as each individual forming their own unique compositions in their minds as they listen. The consequence of imposing a rhythmic organisation is to make some buzzes sound louder than others and to make some intervals seem longer than others although such impressions are an illusion, unwittingly one is projecting themselves into their perception of the environment.

It has been said that pattern finding is the occupation of science and pattern making the occupation of art.

Pattern may be defined as a sequence of events in time, distinguishable from or comparable with another sequence or set, the squares will group and regroup themselves, shifting as we move our eyes about from point to point.

The psychologist William James's had a theory that everything in your consciousness must have a pattern and a meaning that are peculiarly your own, the selection of that pattern is the central task of consciousness.

Consciousness is free within limits to select whatever pattern you like.
