Stylistic approaches

This test piece animation shows how I could display a musical sequence in three dimensions taking advantage of the perception of depth through the computer models use of x,y,z co-ordinates.

If increased amplitude in a soundwave denotes increase in volume we could say that as objects move away from the x axis they increase in volume also. Therefore the rotating concrete blocks are smoothly getting quiter and louder. Care must be taken to get the lighting correct to reinforce this (not successful in this animation).

To take this further, each time the blocks rotate round to the front this will correspond to a period of compression in the sound wave, when lying flat along the horizontal plane this will relate to a state of equilibrium in the wave and when situated furthest away from the camera a period of rarefraction.

Devices to show volume increase could also include variations in colour (warm to cold) or in luminance/glow (light to dark), the latter shown here by the varying glow of the yellow areas.

In terms of a sounds frequency (how often it goes through its cycle per unit of time), this relates to the objects x dimension and how often the object appears in a set x distance. We can introduce ratios of frequencies (2:1 etc) that relate to musical composition.

Further to this a given frequency must be situated logically on the z axis, with higher frequencies at the top and lower frequencies (i:e bass) at the bottom . Higher frequencies with the same volume as low frequencies however usually appear louder so may be pushed forward towards the camera.

I believe this will give my compositions a unified feel and an interesting 'weighting'. This will determine choice of material also, with denser materials (concrete) used at the base.

Interference here is indicated by the shadow variations caused as the result of the motion of two separate elements. This is an element of the process which interests me greatly but is hardest to plan for.
